NAME
  `tablelist::tablelist` - Create and manipulate tablelist widgets
SYNOPSIS

      tablelist::tablelist pathName ?options?

STANDARD OPTIONS

      -borderwidth          -highlightthickness  -setgrid
      -cursor               -relief              -xscrollcommand
      -exportselection      -selectbackground    -yscrollcommand
      -highlightbackground  -selectborderwidth
      -highlightcolor       -selectforeground

  See the options manual entry for details on the standard options. The `-highlightbackground`, `-highlightcolor`, and `-highlightthickness` options are only supported by the Tablelist package, but not by Tablelist_tile. When using the package Tablelist_tile, the options `-selectbackground`, `-selectborderwidth`, and `-selectforeground` have theme-specific default values.
OPTIONS FOR THE BODY COMPONENT OF THE WIDGET

      -background  -disabledforeground  -font  -foreground

  These options (described in the options manual entry) are only valid for the body component of the tablelist widget. As discussed in the next section, the colors and font used when drawing the header labels can be different from those specified for the body. When using the package Tablelist_tile, these options have theme-specific default values.
WIDGET-SPECIFIC OPTIONS

  Command-Line Name: | `-acceptchildcommand`
  Database Name: | `acceptChildCommand`
  Database Class: | `AcceptChildCommand`

  > Specifies a Tcl command used to decide whether a given tablelist node may accept a specified item being moved interactively as a child. The specified command is automatically concatenated with the name of the tablelist widget, the node index of the would-be new parent node, and the row index of the dragged item, the resulting script is evaluated in the global scope, and the return value (which must be a boolean) will determine whether to allow to move the source item to the current mouse position.

  > For example, in the case of a tablelist widget used as a file manager, in which the top-level items represent volumes mounted on the system, the command specified by this option might look like in the (pseudo-)code below:

  > >     proc acceptChildCmd {tbl targetParentNodeIdx sourceRow} {
  > >         if {[string compare $targetParentNodeIdx "root"] == 0} {
  > >             # Allow only volumes as top-level items
  > >             return [expr {[$tbl depth $sourceRow] == 1}]
  > >         } else {
  > >             # Allow only directories as parent items
  > >             return [$targetParentNodeIdx represents a directory]
  > >         }
  > >     }

  > For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this option is not supported for Tk versions earlier than 8.3.

  Command-Line Name: | `-activestyle`
  Database Name: | `activeStyle`
  Database Class: | `ActiveStyle`

  > Specifies how to diplay the active item or element (depending on the value of the `-selecttype` configuration option) when the tablelist has the keyboard focus. The allowed values are `frame`, `none`, and `underline`. The default value `frame` shows a thin frame around the active item or element, which in most cases looks nice. It looks less pretty when applied to the active item if the background color of some of its cells was changed by using the `columnconfigure` or `cellconfigure` widget command and no column separators are shown. The value `none` specifies that no special indication of the active item or element is to be performed. The value `underline` produces the same visual effect as in the case of the Tk core listbox.

  Command-Line Name: | `-arrowcolor`
  Database Name: | `arrowColor`
  Database Class: | `ArrowColor`

  > Specifies the color to use for the up- or down-arrow placed into a column label by the `sortbycolumn` or `sortbycolumnlist` subcommand of the Tcl command associated with the widget. This option is only relevant if the value of the `-showarrow` option is true. The default value depends on the windowing system in the Tablelist package and on the current theme in Tablelist_tile. For example, if the windowing system is `x11` then the default is an empty string, indicating that the arrow will inherit the background color of the label in which it is placed (but is distinguishable from the latter, due to its 3-D border and sunken relief, because in this case the `-arrowstyle` option has the default value `sunken10x9`). On the windowing system `win32`, the default arrow color is `#aca899` for Windows XP, `#569bc0` for Windows Vista and Windows 7, and an empty string for older Windows versions, paired with the default arrow style `flat9x5`, `flat7x4`, and `sunken8x7`, respectively. Finally, for the windowing systems `classic` and `aqua` on the Macintosh, the default arrow color is `#717171` and the default arrow style is `flat7x7`.

  Command-Line Name: | `-arrowdisabledcolor`
  Database Name: | `arrowDisabledColor`
  Database Class: | `ArrowDisabledColor`

  > Specifies the color to use for the up- or down-arrow placed into a column label by the `sortbycolumn` or `sortbycolumnlist` subcommand of the Tcl command associated with the widget when the tablelist's `state` is `disabled`. This option is only relevant if the value of the `-showarrow` option is true. When the default value of the `-arrowcolor` option is an empty string then this is the default for the `-arrowdisabledcolor` option, too; otherwise the latter's default value equals the default foreground color of the header labels in `disabled` state.

  Command-Line Name: | `-arrowstyle`
  Database Name: | `arrowStyle`
  Database Class: | `ArrowStyle`

  > Specifies the relief, width, and height of the up- or down-arrow placed into a column label by the `sortbycolumn` or `sortbycolumnlist` subcommand of the Tcl command associated with the widget. This option is only relevant if the value of the `-showarrow` option is true. The currently supported values are `flat6x4`, `flat7x4`, `flat7x5`, `flat7x7`, `flat8x5`, `flat9x5`, `flat9x6`, `flat9x7`, `flat10x6`, `photo7x7`, `sunken8x7`, `sunken10x9`, and `sunken12x11`, as shown in the picture below. The default value depends on the windowing system in the Tablelist package and on the current theme in Tablelist_tile; see the description of the `-arrowcolor` option for details.

  > While the sort arrows of the styles `flat*` and `sunken*` are created from bitmaps, the arrow style `photo7x7` uses PNG images that look and behave very close to the native sort arrows on Mac OS X Aqua. This arrow style is only supported if the Tk version is either 8.6 (with built-in PNG support), or 8.5 and the `img::png` package can be loaded into the interpreter. When supported, `photo7x7` will be the default value of the `-arrowstyle` option in Tablelist_tile with the `aqua` theme (otherwise `flat7x7` will be used as default). When using this arrow style, the `-arrowcolor` and `-arrowdisabledcolor` options have no effect, but, due to the transparency information contained in the PNG images, the arrows will automatically adapt their color to the various states of the header labels, just like the native sort arrows.

  Command-Line Name: | `-autoscan`
  Database Name: | `autoScan`
  Database Class: | `AutoScan`

  > Specifies a boolean value that controls whether to trigger the automatic scrolling when the mouse leaves the tablelist window with button 1 down. The default is `1`, meaning that automatic scrolling will be in effect, just like in the case of the Tk listbox widget. However, when using the tkdnd package, you might want to set this option to `0`, in order to avoid any conflicts between the drag & drop and the automatic scrolling.

  Command-Line Name: | `-collapsecommand`
  Database Name: | `collapseCommand`
  Database Class: | `CollapseCommand`

  > Specifies a Tcl command to be invoked when collapsing a row of a tablelist used as a tree widget (with the aid of the `collapse` or `collapseall` subcommand). The specified command is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope, before hiding the descendants of the row in question.

  > For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this option is not supported for Tk versions earlier than 8.3.

  Command-Line Name: | `-columns`
  Database Name: | `columns`
  Database Class: | `Columns`

  > Specifies the widths, titles, and alignments of the columns. The option's value must be a list of the form

  > >     width title ?alignment? width title ?alignment? ...

  > Each `width` must be a number. A positive value specifies the column's width in average-size characters of the widget's font. If `width` is negative, its absolute value is interpreted as a column width in pixels. Finally, a value of zero specifies that the column's width is to be made just large enough to hold all the elements in the column, including its header (but no larger than the maximum width indicated by the `-maxwidth` column configuration option). In all three cases, the effective column width will be somewhat greater because of the margins created automatically to the left and right of the column.

  > Each `title` specifies the text to be displayed in the column's header, and may optionally be followed in the next list element by an `alignment`, which specifies how to align the elements of the column. Each `alignment` must be one of `left`, `right`, or `center`. The default is `left`. The `alignment` also refers to the column's title as long as the `-labelalign` option hasn't been specified for that column, or if its value is an empty string.

  > The default value of this option is an empty list, specifying that initially the widget has no columns.

  > REMARK: Columns whose width was specified as zero are called dynamic-width columns. In general, they are more user-friendly than their static-width counterparts, being that their widths are automatically adapted to their contents. On the other hand, the static-width columns perform significantly better on item insertion and sorting than the dynamic-width ones, due to some optimizations introduced in Tablelist version 5.6. (Prior to that release, the above-mentioned operations were faster with dynamic-width columns than with static-width ones.)

  Command-Line Name: | `-columntitles`
  Database Name: | `columnTitles`
  Database Class: | `ColumnTitles`

  > This option provides a simplified form of specifying dynamic-width, left-aligned tablelist columns. Its value is viewed as a list of column titles. The default is an empty list.

  > In the simplest case that no columns have been specified yet, setting this option to the value given by the list

  > >     title title ...

  > is equivalent to setting the `-columns` option to the value given by the list

  > >     0 title left 0 title left ...

  > If the columns have already been specified then this option updates their titles (as many of them as possible) and, if the number of elements of its value is greater than the number of columns then it uses the remaining elements as titles of additional dynamic-width, left-aligned columns. For example, if the widget has 3 columns and the option's value is a list of length 5 then the option will update the titles of the 3 columns and will append 2 new dynamic-width, left-aligned columns having as titles the last 2 elements of the list. If the widget has 3 columns and the option specifies just 2 texts then it will update the titles of the first 2 columns only.

  Command-Line Name: | `-editendcommand`
  Database Name: | `editEndCommand`
  Database Class: | `EditEndCommand`

  > Specifies a Tcl command to be invoked on normal termination of the interactive editing of a cell's contents if the final text of the temporary embedded widget used for the editing is different from its initial one. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, as well as the final contents of the edit window, the resulting script is evaluated in the global scope, and the return value becomes the cell's new contents after destroying the temporary embedded widget. The main purpose of this script is to perform a final validation of the edit window's contents. See the description of the `-forceeditendcommand` option for more about the invocation of the command mentioned above, as well as the INTERACTIVE CELL EDITING section for details on the editing process.

  Command-Line Name: | `-editselectedonly`
  Database Name: | `editSelectedOnly`
  Database Class: | `EditSelectedOnly`

  > Specifies a boolean value that controls whether to start the interactive cell editing when mouse button 1 is pressed in an editable cell. If this value is true then the editing will only be started if the cell has previously been selected (interactively or programmatically). In this case, a first left-click will usually just select the cell (or its row, depending on the value of the `-selecttype` option), and a second mouse click will start the editing session. The default is `0`, meaning that the editing will be started regardless of whether the cell is selected or not.

  Command-Line Name: | `-editstartcommand`
  Database Name: | `editStartCommand`
  Database Class: | `EditStartCommand`

  > Specifies a Tcl command to be invoked when the interactive editing of a cell's contents is started. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, as well as the text displayed in the cell, the resulting script is evaluated in the global scope, and the return value becomes the initial contents of the temporary embedded widget used for the editing. The main purpose of this script is to define validations for the edit window's contents. See the INTERACTIVE CELL EDITING section for details on the editing process.

  Command-Line Name: | `-expandcommand`
  Database Name: | `expandCommand`
  Database Class: | `ExpandCommand`

  > Specifies a Tcl command to be invoked when expanding a row of a tablelist used as a tree widget (with the aid of the `expand` or `expandall` subcommand). The specified command is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope, before displaying the children of the row in question.

  > For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this option is not supported for Tk versions earlier than 8.3.

  > REMARK: It is common practice to use the command specified as the value of this option to insert the children of the row that is about to be expanded, if it has no children yet. For example, the Directory Viewer demo script uses the command implemented as follows:

  > >     proc expandCmd {tbl row} {
  > >         if {[$tbl childcount $row] == 0} {
  > >             # Get the name of the directory whose leaf name is
  > >             # displayed in the first cell of the specified row
  > >             set dir [$tbl rowattrib $row pathName]

  > >             # Display the contents of the directory $dir
  > >             # as child items of the one identified by $row
  > >             putContents $dir $tbl $row
  > >         }

  > >         # The rest is just eye candy:
  > >         if {[$tbl childcount $row] != 0} {
  > >             # Update the image displayed in the row's first cell
  > >             $tbl cellconfigure $row,0 -image openFolderImg
  > >         }
  > >     }

  Command-Line Name: | `-forceeditendcommand`
  Database Name: | `forceEditEndCommand`
  Database Class: | `ForceEditEndCommand`

  > Specifies a boolean value that controls the invocation of the command given by the the `-editendcommand` option. If this value is true then the command will be invoked on normal termination of the editing process even if the final text of the temporary embedded widget used for the editing equals its initial one, and will also be invoked when the interactive cell editing is canceled (in the latter case, the text passed to it as last argument will be the cell's original contents, not its final one). The default value of this option is `0`, meaning that the command will only be invoked on normal termination of the editing process, if the final text of the temporary embedded widget is different from its initial one. See the INTERACTIVE CELL EDITING section for details on the editing process.

  > If the option's value is true and no value for the `-editendcommand` option was specified, then on normal termination of the editing process the cell's new contents will be set to the text contained in the edit window, even if it has not been changed interactively (but might have been returned by the command given by the the `-editstartcommand` option).

  > Setting this option to true enables you to execute an arbitrary action whenever the interactive cell editing is finished. Just binding a script to the `<Destroy>` event for the temporary embedded widget used for the editing won't work, because that widget might be destroyed and recreated automatically under various circumstances. Alternately, you can use the `<<TablelistCellUpdated>>` and `<<TablelistCellRestored>>` virtual events, generated by the `finishediting` and `cancelediting` subcommands, respectively.

  Command-Line Name: | `-fullseparators`
  Database Name: | `fullSeparators`
  Database Class: | `FullSeparators`

  > Specifies a boolean value that controls whether the separators (if any) shall extend all of the way to the bottom of the tablelist's body. The default is `0`, meaning that the height of the separators will be adjusted to the widget's content, i.e., they won't extend to the bottom of the tablelist's body if there is free vertical space left below the widget's last row.

  Command-Line Name: | `-height`
  Database Name: | `height`
  Database Class: | `Height`

  > Specifies the desired height for the window, in lines. If zero or less then the desired height for the window is made just large enough to hold the header and all the items in the tablelist widget, provided that no column-, row-, or cell-specific fonts are used and no embedded images or windows are displayed in the widget's cells.

  Command-Line Name: | `-incrarrowtype`
  Database Name: | `incrArrowType`
  Database Class: | `IncrArrowType`

  > Specifies the type of the arrow placed into a column label when sorting the items based on that column in increasing order, with the aid of the `sortbycolumn` or `sortbycolumnlist` subcommand of the Tcl command associated with the widget. The value of this option must be one of `up` or `down`. The default is `up`. This option is only relevant if the value of the `-showarrow` option is true.

  Command-Line Name: | `-labelactivebackground`
  Database Name: | `labelActiveBackground`
  Database Class: | `Foreground`

  > Specifies the `-activebackground` option for the header labels, i.e., the background color to use when the mouse cursor is positioned over a header label and the value of `tk_strictMotif` is false. This option is only defined in the Tablelist package if the Tk version being used supports the `-activebackground` option for label widgets. This is checked by Tablelist at initialization time, and will normally be the case for Tk versions 8.3.2 or higher. On the other hand, the Tablelist_tile package doesn't support the `-labelactivebackground` option.

  Command-Line Name: | `-labelactiveforeground`
  Database Name: | `labelActiveForeground`
  Database Class: | `Background`

  > Specifies the `-activeforeground` option for the header labels, i.e., the foreground color to use when the mouse cursor is positioned over a header label and the value of `tk_strictMotif` is false. This option is only defined in the Tablelist package if the Tk version being used supports the `-activeforeground` option for label widgets. This is checked by Tablelist at initialization time, and will normally be the case for Tk versions 8.3.2 or higher. On the other hand, the Tablelist_tile package doesn't support the `-labelactiveforeground` option.

  Command-Line Name: | `-labelbackground` or `-labelbg`
  Database Name: | `labelBackground`
  Database Class: | `Background`

  > Specifies the `-background` option for the header labels. This option is only supported by the Tablelist package, but not by Tablelist_tile.

  Command-Line Name: | `-labelborderwidth` or `-labelbd`
  Database Name: | `labelBorderWidth`
  Database Class: | `BorderWidth`

  > Specifies the `-borderwidth` option for the header labels. This option is different from the standard `-borderwidth` option defined for the tablelist widget itself. In the package Tablelist_tile this option has a theme-specific default value.

  Command-Line Name: | `-labelcommand`
  Database Name: | `labelCommand`
  Database Class: | `LabelCommand`

  > Specifies the Tcl command to be invoked when mouse button 1 is pressed over one of the header labels and later released over the same label. When the `<ButtonRelease-1>` event occurs, the command is automatically concatenated with the name of the tablelist widget and the column index of the respective label, and the resulting script is evaluated in the global scope. If the tablelist's `state` is `disabled` then this action will not take place. The most common value of this option is `tablelist::sortByColumn`; this command sorts the items based on the column whose index was passed to it as second argument.

  Command-Line Name: | `-labelcommand2`
  Database Name: | `labelCommand2`
  Database Class: | `LabelCommand2`

  > Specifies the Tcl command to be invoked when mouse button 1 is pressed together with the `Shift` key over one of the header labels and later released over the same label. When the `<ButtonRelease-1>` event occurs, the command is automatically concatenated with the name of the tablelist widget and the column index of the respective label, and the resulting script is evaluated in the global scope. If the tablelist's `state` is `disabled` then this action will not take place. The most common value of this option is `tablelist::addToSortColumns`; this command adds the column index passed to it as second argument to the list of sort columns and sorts the items based on the columns indicated by the modified list.

  Command-Line Name: | `-labeldisabledforeground`
  Database Name: | `labelDisabledForeground`
  Database Class: | `DisabledForeground`

  > Specifies the `-disabledforeground` option for the header labels, i.e., the foreground color to use for the labels when the tablelist's `state` is `disabled`. This option is only defined in the Tablelist package if the Tk version being used supports the `-disabledforeground` option for label widgets. This is checked by Tablelist at initialization time, and will normally be the case for Tk versions 8.3.1 or higher. On the other hand, the Tablelist_tile package doesn't support the `-labeldisabledforeground` option.

  Command-Line Name: | `-labelfont`
  Database Name: | `labelFont`
  Database Class: | `Font`

  > Specifies the `-font` option for the header labels. In the package Tablelist_tile this option has a theme-specific default value.

  Command-Line Name: | `-labelforeground` or `-labelfg`
  Database Name: | `labelForeground`
  Database Class: | `Foreground`

  > Specifies the `-foreground` option for the header labels. In the package Tablelist_tile this option has a theme-specific default value.

  Command-Line Name: | `-labelheight`
  Database Name: | `labelHeight`
  Database Class: | `Height`

  > Specifies the `-height` option for the header labels. This option is only supported by the Tablelist package, but not by Tablelist_tile.

  Command-Line Name: | `-labelpady`
  Database Name: | `labelPadY`
  Database Class: | `Pad`

  > In the Tablelist package this option specifies the `-pady` configuration option for the header labels. In the Tablelist_tile package the value of the `-labelpady` option is mapped to the corresponding components of the value of the `-padding` configuration option of the header labels, and the `-labelpady` option has a theme-specific default value.

  Command-Line Name: | `-labelrelief`
  Database Name: | `labelRelief`
  Database Class: | `Relief`

  > Specifies the `-relief` option for the header labels. This option is different from the standard `-relief` option defined for the tablelist widget itself. The default value is `raised`.

  Command-Line Name: | `-listvariable`
  Database Name: | `listVariable`
  Database Class: | `Variable`

  > Specifies the name of a variable. The value of the variable is a list to be displayed inside the widget; if the variable value changes then the widget will automatically update itself to reflect the new value. The value of the variable must be a valid list. Each list element corresponds to a row within the widget, and must be a valid list itself; its elements correspond to the cells within the respective row. Attempts to assign a variable whose value does not fulfil these conditions to `-listvariable` will cause an error. Attempts to unset a variable in use as a `-listvariable` will fail but will not generate an error.

  > REMARK 1: For increased efficiency, updating the widget to reflect a changed value of the variable specified with this option is, whenever possible, done at idle time (i.e., when there are no events to process). On the other hand, most tablelist subcommands make it necessary to perform an immediate update of the widget's internal list according to the value of this variable, before executing the subcommand in question. Doing this repeatedly can become quite inefficient. To avoid performance problems, you should always try to separate the operations that build up the value of the variable specified by this option from other commands. For example, instead of

  > >     tablelist::tablelist .tbl ... -listvariable var
  > >     set var {}
  > >     for {set row 0} {$row < 1000} {incr row} {
  > >         lappend var ...
  > >         .tbl cellconfigure $row,3 -image ...
  > >     }

  > you should write

  > >     tablelist::tablelist .tbl ... -listvariable var
  > >     set var {}
  > >     for {set row 0} {$row < 1000} {incr row} {
  > >         lappend var ...
  > >     }
  > >     for {set row 0} {$row < 1000} {incr row} {
  > >         .tbl cellconfigure $row,3 -image ...
  > >     }

  > The first method above is quite inefficient, because it requires 1000 updates of the widget's internal list. The second method performs incomparably faster, because it needs only one synchronization (at the beginning of the second loop).

  > REMARK 2: It is not recommended to set this option for a tablelist used as a tree widget, because adding new items to the list specified as its value will result in inserting those list elements into the widget without respecting the tree's internal structure. There is no problem if you access the variable for reading only, but for that purpose it is more efficient to use the `itemlistvar` subcommand rather than the `-listvariable` option.

  Command-Line Name: | `-movablecolumns`
  Database Name: | `movableColumns`
  Database Class: | `MovableColumns`

  > Specifies a boolean value that determines whether the columns can be moved interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section below for information on moving a column interactively. The default value is `0`.

  Command-Line Name: | `-movablerows`
  Database Name: | `movableRows`
  Database Class: | `MovableRows`

  > Specifies a boolean value that determines whether the rows can be moved interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE TABLELIST BODY section below for information on moving a row interactively. The default value is `0`.

  Command-Line Name: | `-movecolumncursor`
  Database Name: | `moveColumnCursor`
  Database Class: | `MoveColumnCursor`

  > Specifies the mouse cursor to be used when moving a column interactively. The default value is `icon` on the windowing systems `x11` and `win32`, and the native cursor `closedhand` on the Macintosh windowing systems `classic` and `aqua`.

  Command-Line Name: | `-movecursor`
  Database Name: | `moveCursor`
  Database Class: | `MoveCursor`

  > Specifies the mouse cursor to be used when moving a row interactively. The default value is `hand2` on the windowing systems `x11` and `win32`, and the native cursor `pointinghand` on the Macintosh windowing systems `classic` and `aqua`.

  Command-Line Name: | `-populatecommand`
  Database Name: | `populateCommand`
  Database Class: | `PopulateCommand`

  > Specifies a Tcl command to be invoked by the `searchcolumn` subcommand before examining the children (or descendants, when used with the `-descend` option) of a tablelist row whose children have not been inserted yet. The specified command is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope. It is expected that this script will insert the children of the row in question, without expanding the node or changing its appearance in any other way.

  > For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this option is not supported for Tk versions earlier than 8.3.

  > REMARK: There are many similarities between this option and `-expandcommand`. Both options are used int the first place to insert children on demand. The main differences between them are as follows:

  > 1. The command specified by the `-populatecommand` option is only invoked for rows whose children have not been inserted yet, while the one specified by `-expandcommand` is always invoked before expanding a row, regardless of whether the children of that row are already present in the widget or not.
  > 2. The command specified by the `-expandcommand` option may perform visual changes on the node in question, while the role of the one specified by `-populatecommand` is restricted to inserting the children, without altering the node's appearance in any way.

  > A logical consequence of the above is that the value of `-populatecommand` is usually just a stripped-down version of the command specified by the `-expandcommand` option. For example, the Directory Viewer demo script might use a command implemented as follows:

  > >     proc populateCmd {tbl row} {
  > >         # Get the name of the directory whose leaf name is
  > >         # displayed in the first cell of the specified row
  > >         set dir [$tbl rowattrib $row pathName]

  > >         # Display the contents of the directory $dir
  > >         # as child items of the one identified by $row
  > >         putContents $dir $tbl $row
  > >     }

  > Moreover, the `-expandcommand` option can be set to a command that invokes the one specified by the `-populatecommand` option:

  > >     proc expandCmd {tbl row} {
  > >         if {[$tbl childcount $row] == 0} {
  > >             populateCmd $tbl $row
  > >         }

  > >         # The rest is just eye candy:
  > >         if {[$tbl childcount $row] != 0} {
  > >             # Update the image displayed in the row's first cell
  > >             $tbl cellconfigure $row,0 -image openFolderImg
  > >         }
  > >     }

  Command-Line Name: | `-protecttitlecolumns`
  Database Name: | `protectTitleColumns`
  Database Class: | `ProtectTitleColumns`

  > Specifies a boolean value that determines whether the boundary of the title column area shall be protected from being crossed when moving a column interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section below for information on moving a column interactively. The default value is `0`, specifying that non-title columns can be moved into the title column area and vice-versa.

  Command-Line Name: | `-resizablecolumns`
  Database Name: | `resizableColumns`
  Database Class: | `ResizableColumns`

  > Specifies a boolean value that determines whether the columns can be resized interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section below for information on interactive column resizing. The default value is `1`.

  Command-Line Name: | `-resizecursor`
  Database Name: | `resizeCursor`
  Database Class: | `ResizeCursor`

  > Specifies the mouse cursor to be used during interactive column resizing. The default value is `sb_h_double_arrow` on the windowing systems `x11` and `win32`, and the native cursor `resizeleftright` on the Macintosh windowing systems `classic` and `aqua`.

  Command-Line Name: | `-selectmode`
  Database Name: | `selectMode`
  Database Class: | `SelectMode`

  > Specifies one of several styles for manipulating the selection. The value of the option may be arbitrary, but the default bindings expect it to be either `single`, `browse`, `multiple`, or `extended`. The default value is `browse`.

  Command-Line Name: | `-selecttype`
  Database Name: | `selectType`
  Database Class: | `SelectType`

  > Specifies one of two selection types for the tablelist widget: `row` or `cell`. If the selection type is `row` then the default bindings will select and deselect entire items, and the whole row having the location cursor will be displayed as active when the tablelist has the keyboard focus. If the selection type is `cell` then the default bindings will select and deselect individual elements, and the single cell having the location cursor will be displayed as active when the tablelist has the keyboard focus. The default value is `row`.

  Command-Line Name: | `-setfocus`
  Database Name: | `setFocus`
  Database Class: | `SetFocus`

  > Specifies a boolean value that determines whether a click with the left mouse button anywhere into the tablelist's body, including the separators and the embedded images (more precisely, any descendants of the tablelist widget having the binding tag `TablelistBody`) should set the focus to the body of the tablelist widget if the latter's `state` is `normal`. The default value is `1`.

  Command-Line Name: | `-showarrow`
  Database Name: | `showArrow`
  Database Class: | `ShowArrow`

  > Specifies a boolean value that determines whether the `sortbycolumn` and `sortbycolumnlist` subcommands of the Tcl command associated with the widget should place an arrow indicating the sort order into the header label(s) of the column(s) specified by their first argument. The default value is `1`.

  Command-Line Name: | `-showlabels`
  Database Name: | `showLabels`
  Database Class: | `ShowLabels`

  > Specifies a boolean value that determines whether the header labels are to be shown or not. The default value is `1`.

  Command-Line Name: | `-showseparators`
  Database Name: | `showSeparators`
  Database Class: | `ShowSeparators`

  > Specifies a boolean value that determines whether the columns are to be separated with borders. The default value is `0`. The separators are implemented as thin frames with sunken relief in the package Tablelist, and as tile separator widgets in the package Tablelist_tile. They are attached to the right edges of the header labels, and are only created if the value of this option is true. There is no support for horizontal separators in tablelist widgets, but a nice distinguishing effect for the rows can be achieved with the aid of the `-stripebackground` option discussed below.

  Command-Line Name: | `-snipstring`
  Database Name: | `snipString`
  Database Class: | `SnipString`

  > Specifies the string to be used as snip indicator when displaying the elements that don't fit into their cells. The default is an ellipsis (`"..."`).

  Command-Line Name: | `-sortcommand`
  Database Name: | `sortCommand`
  Database Class: | `SortCommand`

  > Specifies a command to be used for the comparison of the items when invoking the `sort` subcommand of the Tcl command associated with the tablelist widget. To compare two items (viewed as lists of cell contents within one row each) during the `sort` operation, the command is automatically concatenated with the two items and the resulting script is evaluated. The script should return an integer less than, equal to, or greater than zero if the first item is to be considered less than, equal to, or greater than the second, respectively.

  Command-Line Name: | `-spacing`
  Database Name: | `spacing`
  Database Class: | `Spacing`

  > Specifies additional space to provide above and below each row of the widget. The option's value may have any of the standard forms for screen distances. It defaults to `0`.

  Command-Line Name: | `-state`
  Database Name: | `state`
  Database Class: | `State`

  > Specifies one of two states for the tablelist widget: `normal` or `disabled`. If the widget is disabled then neither items nor columns may be inserted, deleted, updated, or moved, the items, header labels, and the up- or down-arrow are drawn in the `-disabledforeground`, `-labeldisabledforeground`, and `-arrowdisabledcolor` color, respectively, the selection cannot be modified and is not shown (although the selection information is retained), the header labels are completely insensitive, and no interactive cell editing can be performed. In addition, in disabled state any color options specified at column, row, or cell level will be ignored.

  Command-Line Name: | `-stretch`
  Database Name: | `stretch`
  Database Class: | `Stretch`

  > Specifies the columns to be stretched in order to fill the tablelist window if necessary. The option's value may be `all` or a list of column indices in any of the forms described in the COLUMN INDICES section below. In the second case, the specified column indices are replaced with their numerical equivalents, except for the index `end`, which is viewed as a dynamic column index whose numerical equivalent might change during program execution and therefore will be recomputed every time the columns are stretched. The list will be updated automatically whenever columns are inserted, deleted, or moved. The number of pixels by which a column is stretched is proportional to its width in pixels. The default value of this option is an empty list, meaning that no column will be stretched to eliminate the blank space that might appear at the right of the table. (Note that the blank space following the header labels is filled with a dummy, insensitive label having the same background, borderwidth, and relief as the "normal" header labels.) This option is ignored if the value of the `-width` configuration option is zero or less.

  Command-Line Name: | `-stripebackground` or `-stripebg`
  Database Name: | `stripeBackground`
  Database Class: | `Background`

  > Specifies the background color to use when displaying the items belonging to a stripe. Each stripe is composed of the same number `stripeHeight` of consecutive non-hidden items, according to the value of the `-stripeheight` configuration option. The first `stripeHeight` non-hidden items are "normal" ones; they are followed by a stripe composed of the next `stripeHeight` non-hidden items, which in turn is followed by the same number of "normal" non-hidden items, and so on. In the Tablelist package and in most themes supported by Tablelist_tile, the default value is an empty string, indicating that the stripes will inherit the background color specified by the `-background` configuration option. When using Tablelist_tile with the `tileqt` theme then the default value is given by the global KDE option `alternateBackground`, which in turn depends on the current color scheme. In this case it is recommended to either keep that default value retrieved from KDE, or to use an explicitly specified empty string if no stripes are to be displayed. The `-stripebackground` option has a higher priority than the `-background` column configuration option, but a lower priority than the `-background` option specified at row or cell level.

  Command-Line Name: | `-stripeforeground` or `-stripefg`
  Database Name: | `stripeForeground`
  Database Class: | `Foreground`

  > Specifies the foreground color to use when displaying the items belonging to a stripe. Each stripe is composed of the same number `stripeHeight` of consecutive non-hidden items, according to the value of the `-stripeheight` configuration option. The first `stripeHeight` non-hidden items are "normal" ones; they are followed by a stripe composed of the next `stripeHeight` non-hidden items, which in turn is followed by the same number of "normal" non-hidden items, and so on. The default value is an empty string, indicating that the stripes will inherit the foreground color specified by the `-foreground` configuration option. The `-stripeforeground` option has a higher priority than the `-foreground` column configuration option, but a lower priority than the `-foreground` option specified at row or cell level.

  Command-Line Name: | `-stripeheight`
  Database Name: | `stripeHeight`
  Database Class: | `StripeHeight`

  > Specifies the number of items in each stripe. If zero or less then no stripes are displayed. The default is `1`.

  Command-Line Name: | `-takefocus`
  Database Name: | `takeFocus`
  Database Class: | `TakeFocus`

  > This option determines whether the widget accepts the focus during keyboard traversal. It is almost identical to the standard option of the same name (see the options manual entry for details). The only difference is that not the widget itself but its body child (containing the items) will receive the focus during keyboard traversal with the standard keys (`Tab` and `Shift-Tab`).

  Command-Line Name: | `-targetcolor`
  Database Name: | `targetColor`
  Database Class: | `TargetColor`

  > Specifies the color of the temporary gap displayed in the tablelist's body or header to indicate the target position when moving a row or column interactively. The default value is `black`.

  Command-Line Name: | `-titlecolumns`
  Database Name: | `titleColumns`
  Database Class: | `TitleColumns`

  > Specifies the number of the non-scrollable columns at the left edge of the window, also called title columns. The positions of these columns will not change when adjusting the horizontal view by invoking the `scan`, `seecell`, `seecolumn`, or `xview` subcommand. The default value is `0`. The value of this option also determines the scrolling unit used by the commands mentioned above when shifting the horizontal view: if it is positive then the horizontal scrolling is performed column-wise, otherwise by character units (the width of the `0` character).

  > The end of the title column area is visualized with the aid of a separator, attached to the right edge of the header label corresponding to the last non-hidden title column. This special separator is always displayed to mark the end of the title columns (if any), independently of the value of the `-showseparators` option. The user can easily distinguish it from the other separators by means of its background color, which is different from that of the other separators.

  > For technical reasons (the use of the `-elide` option for a text widget tag), this option is not supported for Tk versions earlier than 8.3.

  Command-Line Name: | `-tooltipaddcommand`
  Database Name: | `tooltipAddCommand`
  Database Class: | `TooltipAddCommand`

  > Specifies a Tcl command to be used for displaying cell- and column label-specific balloon help. When the mouse pointer enters a cell, the command is automatically concatenated with the name of the tablelist widget and the cell's row and column indices, and the resulting script is evaluated in the global scope. Similarly, when the mouse pointer enters a header label, the command is automatically concatenated with the name of the tablelist widget, the number `-1`, and the column index of the respective label, and the resulting script is evaluated in the global scope. In both cases, the action described above is only triggered if both the value of this option and that of `-tooltipdelcommand` are nonempty strings.

  > For example, consider the procedure `tooltipAddCmd` shown below, which makes use of the `DynamicHelp::add` command from the BWidget package to display the full cell and label texts as tooltips for the cells and header labels with snipped contents.

  > >     proc tooltipAddCmd {tbl row col} {
  > >         if {($row >= 0 && [$tbl iselemsnipped $row,$col fullText]) ||
  > >             ($row <  0 && [$tbl istitlesnipped $col fullText])} {
  > >             DynamicHelp::add $tbl -text $fullText
  > >         }
  > >     }

  > A tablelist widget can use this procedure by specifying

  > >     ... -tooltipaddcommand tooltipAddCmd -tooltipdelcommand DynamicHelp::delete

  > If you prefer to use the `tooltip::tooltip` command from the tooltip package contained in tklib then the procedure becomes

  > >     proc tooltipAddCmd {tbl row col} {
  > >         if {($row >= 0 && [$tbl iselemsnipped $row,$col fullText]) ||
  > >             ($row <  0 && [$tbl istitlesnipped $col fullText])} {
  > >             tooltip::tooltip $tbl $fullText
  > >         }
  > >     }

  > and can be used by specifying

  > >     ... -tooltipaddcommand tooltipAddCmd -tooltipdelcommand "tooltip::tooltip clear"

  > Please note that in the less common case that the name of your tablelist widget contains spaces, the`tooltip::tooltip clear`command won't work as expected. As a workaround you can use the slightly modified approach shown below:

  > >     proc tooltipDelCmd tbl { tooltip::tooltip $tbl "" }

  > >     ... -tooltipaddcommand tooltipAddCmd -tooltipdelcommand tooltipDelCmd

  > Both examples above make use of the `iselemsnipped` and `istitlesnipped` subcommands, to make sure that the full cell and label texts will only be displayed for those cells and header labels whose contents are snipped.

  Command-Line Name: | `-tooltipdelcommand`
  Database Name: | `tooltipDelCommand`
  Database Class: | `TooltipDelCommand`

  > Specifies a Tcl command to be used for removing the cell- or column label-specific balloon help. When the mouse pointer leaves a cell or a header label, the command specified by this option is automatically concatenated with the name of the tablelist widget and the resulting script is evaluated in the global scope. This action is only triggered if both the value of this option and that of `-tooltipaddcommand` are nonempty strings. Common values for this option are `"DynamicHelp::delete"` (which requires the BWidget package) and `"tooltip::tooltip clear"` (which requires the tooltip package contained in tklib). Their usage is shown in the examples above.

  Command-Line Name: | `-treecolumn`
  Database Name: | `treeColumn`
  Database Class: | `TreeColumn`

  > Specifies the column to contain the indentations and expand/collapse controls for a tablelist used as a tree widget. The option's value may be a column index in any of the forms described in the COLUMN INDICES section below. The specified column index is replaced with its numerical equivalent, and it will be updated automatically whenever columns are inserted, deleted, or moved. The default value is `0`.

DESCRIPTION
  The `tablelist::tablelist` command creates a new window named `pathName` and of the class `Tablelist`, and makes it into a tablelist widget. Additional options, described above, may be specified on the command line or in the option database to configure aspects of the tablelist such as its colors, font, and columns. The `tablelist::tablelist` command returns its `pathName` argument. At the time this command is invoked, there must not exist a window named `pathName`, but `pathName`'s parent must exist.
  A tablelist is a multi-column listbox and tree widget, implemented as a mega-widget, consisting of a body and a header. The body displays a list of items, one per line. Each item is a list of elements, which are aligned in columns. In other words, an item is the contents of a row, and an element is the text contained in a cell. The header consists of label widgets displaying the column titles. The labels can be used, among others, for interactive column resizing and column-based sorting of the items, as described below.
  Each cell and each header label of a tablelist widget can also contain an image, which is placed to the left or right of the text, depending on the column's alignment. Instead of an image, a tablelist cell can also contain an embedded window, placed to the left or right of the text, just like an embedded image.
  When a tablelist is used as a tree widget, one of its columns will display the tree hierarchy with the aid of indentations and expand/collapse controls. The Tablelist package provides a great variety of tree styles controlling the look & feel of that column, and chooses the correct default style depending on the windowing system, operating system version, and tile theme. In a tablelist used as a multi-column tree widget, every row is at the same time a tree node, having exactly one parent node and any number of child nodes. The tree's origin is the invisible root node, which has no parent itself and whose children are the top-level nodes.
  The elements of a tablelist widget can, per default, be only edited programmatically. However, interactive editing can be enabled for individual cells and for entire columns. Per default, the interactive cell editing uses a temporary embedded entry widget, thus making sure that all the validation facilities available for entry widgets can be used during the editing process. A great variety of widgets from the packages BWidget, Iwidgets, combobox (by Bryan Oakley), and Mentry (or Mentry_tile), as well as Tk core text, spinbox, checkbutton, and menubutton widgets, along with tile entry, spinbox, combobox, checkbutton, and menubutton widgets are also supported as temporary embedded widgets used for cell editing. In addition, a rich set of keyboard bindings is provided for a comfortable navigation between the editable cells.
  When first created, a new tablelist widget has no items. Items may be added, deleted, or updated using widget commands described below. In addition, one or more items or elements may be selected. If a tablelist widget is exporting its selection (see the `-exportselection` option), then it will observe the standard X11 protocols for handling the selection. Tablelist widget selections are available as types `STRING` and `UTF8_STRING`; the value of the selection will be a text built by taking all of the rows having at least one non-hidden selected element, joining these elements together with tabs, and the resulting strings in turn with newlines. If a tablelist widget that is exporting its selection is the selection owner and some other window claims ownership of the selection away from it, then the virtual event `<<TablelistSelectionLost>>` is generated.
  It is not necessary for all the elements to be displayed in the tablelist widget at once; commands described below may be used to change the view in the window. Tablelist widgets allow scrolling in both directions using the standard `-xscrollcommand` and `-yscrollcommand` options. They also support scanning, as described below.
  Each tablelist widget, as well as each tablelist column, row, and cell may have any number of attributes, which can be used in commands that create or manipulate tablelist widgets for particular purposes.
COLORS AND FONTS
  The `-background`, `-font`, `-foreground`, `-selectbackground`, and `-selectforeground` options can also be specified at column, row, and cell level, by using the `columnconfigure` (or `configcolumnlist`, or `configcolumns`), `rowconfigure` (or `configrowlist`, or `configrows`), and `cellconfigure` (or `configcelllist`, or `configcells`) subcommands of the Tcl command associated with the tablelist widget. For this reason, a particular cell can have up to four values for one and the same color or font option. If these values conflict, then the option specified at the highest priority level is used. The decreasing priority order is cell, row, column, widget.

  If one of these options hasn't been specified at cell, row, or column level, or if its value for that level is an empty string (this is explicitly allowed), then that option will not be used at that particular level.

COLUMN CONFIGURATION OPTIONS
  The following options are currently supported by the `columncget`, `columnconfigure`, `configcolumnlist`, and `configcolumns` commands:
  `-align alignment`
    Specifies how to align the elements of the column. It must be one of `left`, `right`, or `center`. This option also refers to the column's title if the `-labelalign` option hasn't been specified for the given column, or if its value is an empty string. The `-align` option is tied to the `alignment` element corresponding to this column in the list specifying the value of the `-columns` option for the tablelist widget; changes in either will automatically be reflected in the other.
  `-background color` or `-bg color`
    Specifies the normal background color to use when displaying the contents of the column.
  `-changesnipside boolean`
    Specifies whether to override the alignment-specific default position of the snip indicator when displaying the elements of the column (excluding its title). The default value is `0`, meaning that the snip string will be appended to the elements if the column's alignment is `left` or `center` and prepended to them in case the alignment is `right`.
  `-editable boolean`
    Specifies whether the elements of the column can be edited interactively. The default value is `0`. The value of this option can be overridden for individual cells by using the cell configuration option of the same name.
  `-editwindow name`
    Specifies the type of the temporary embedded widget to be used for interactive editing of the contents of the given column's cells. `name` may be one of `entry` (which is the default), `text`, `spinbox` (the latter for Tk versions 8.4 or higher), `checkbutton`, `menubutton`, `ttk::entry`, `ttk::spinbox`, `ttk::combobox`, `ttk::checkbutton`, or `ttk::menubutton` (the latter five only in the presence of the tile widget engine), or the value returned by one of the registration commands for widgets from the packages BWidget, Iwidgets, combobox (by Bryan Oakley), and Mentry (or Mentry_tile). For example, you can use `-editwindow ComboBox` after registering the ComboBox widget for interactive cell editing with the aid of the `tablelist::addBWidgetComboBox` command. Similarly, you can use `-editwindow combobox` after registering Bryan Oakley's combobox widget for interactive cell editing by invoking the `tablelist::addOakleyCombobox` command. The value of this option can be overridden for individual cells by using the cell configuration option of the same name.
  `-font font`
    Specifies the font to use when displaying the contents of the column.
  `-foreground color` or `-fg color`
    Specifies the normal foreground color to use when displaying the contents of the column.
  `-formatcommand command`
    Specifies a Tcl command to be invoked when displaying the content of a cell within this column or adding it to the selection when the latter is being exported. If `command` is a nonempty string, then it is automatically concatenated with the cell's text, the resulting script is evaluated in the global scope, and the return value is displayed in the cell or added to the selection instead of the original data.

    For example, if a time value in seconds is being inserted into the cell and `command` is the procedure `formatDate` defined as

    >     proc formatDate clockVal {
    >         return [clock format $clockVal -format "%Y-%m-%d"]
    >     }

    then the text displayed in the cell will be the date in the specified format, not the time value in seconds.

    This option is also used by Tablelist when building the return values of the `getformatted`, `getformattedcolumns`, and `getformattedcells` subcommands, or searching for a text pattern passed to the `searchcolumn` subcommand with the `-formatted` option. All the other subcommands, notably `get`, `getcolumns`, `getcells`, `rowcget`, `columncget`, `cellcget`, `sort`, `sortbycolumn`, `sortbycolumnlist`, and `refreshsorting` operate on the original cell text, which is contained in the widget's internal list. In the case of the above example, this will make it possible to sort the items quite easily by time, with a second's precision, even if their visual representation only contains the year, month, and day.

    The `-formatcommand` option comes in handy if only images or embedded windows are to be displayed in a column but the texts associated with the cells may not simply be empty strings because they are needed for other purposes (like sorting or editing). In such cases, a procedure returning an empty string can be used as the option's value, thus making sure that the textual information contained in that column remains hidden.

    The demo scripts included in the Tablelist distribution contain further examples demonstrating the use of this option. The most interesting ones are also described in Tablelist Programmer's Guide.

    In the more sophisticated case that the result of the formatting should also depend on the cell's row, you will have to invoke the `formatinfo` subcommand, which provides the necessary information about the cell whose content is being formatted.

    Due to the `-formatcommand` column configuration option, we will distinguish between the internal value of a tablelist element and its formatted version. The latter is the result of the invocation of the script corresponding to the `-formatcommand` option of the element's column, or the element itself if this option was not set for that column. Consequently, the formatted version of a tablelist item is a list comprised of the formatted elements of the original item.

  `-hide boolean`
    Specifies whether to hide the column when displaying the widget or exporting its selection. The default value is `0`. After toggling the hidden state of a column, the `<<TablelistColHiddenStateChanged>>` virtual event is generated.
  `-labelalign alignment`
    Specifies how to align the column's title. It must be one of `left`, `right`, or `center`, or an empty string. If this option hasn't been specified for the given column, or if its value is an empty string, then the header title will have the same alignment as the elements of the column, as given by the `-align` column configuration option or by the `alignment` element corresponding to this column in the list specifying the value of the `-columns` global option.
  `-labelbackground color` or `-labelbg color`
  `-labelborderwidth screenDistance` or `-labelbd screenDistance`
  `-labelcommand command`
  `-labelcommand2 command`
  `-labelfont fontName`
  `-labelforeground color` or `-labelfg color`
  `-labelheight lines`
  `-labelpady screenDistance`
  `-labelrelief relief`
    The value of each of these options may also be an empty string. These options are the column-specific equivalents of the global ones having the same names, described in the WIDGET-SPECIFIC OPTIONS section. They override the options of the same names set at widget level if the specified value is not empty. If one of these options hasn't been specified for the given column, or if its value is an empty string, then that option will not be used at column level; the global option of the same name will be used instead. The `-labelactivebackground`, `-labelactiveforeground`, and `-labeldisabledforeground` options are only defined at widget level; there are no column configuration options with these names. The `-labelbackground` and `-labelheight` options are only supported by the Tablelist package, but not by Tablelist_tile.
  `-labelimage image`
    Specifies the name of the Tk image to be displayed in the header label. `image` must be the result of an invocation of the `image create` command, or an empty string, specifying that no image is to be displayed. If the label's text is right-aligned then the image will be displayed to the right of the text, otherwise to its left. The text and the image are separated from each other by a gap corresponding to the width of a space character in the given label's font.
  `-maxwidth width`
    `width` must be a number. A positive value specifies the column's maximum width in average-size characters of the widget's font. If `width` is negative, its absolute value is interpreted as a maximum column width in pixels. Finally, a value of zero (which is the default) specifies that the column's maximum width is to be made just large enough to hold all the elements in the column, including its header. This option is only relevant if the given column has dynamic width, i.e., if its width was set to `0`.
  `-name name`
    Specifies a name associated with the column. While the numerical index of a column might change by inserting, deleting, or moving columns, its name remains constant and can be used as a safe alternative column index (see the COLUMN INDICES section for details). Similarly, it can also be used as the second component of a cell index of the form `row,col`, as described in the CELL INDICES section. To avoid ambiguities, column names should be different from any other forms of column indices (like numbers, `active`, `anchor`, `end`, `left`, `right`, or any of their abbreviations). They should also be different from (any abbreviations of) the string `all`, which may be specified as the value of the `-stretch` configuration option. The default value is an empty string.
  `-resizable boolean`
    Specifies whether the column can be resized interactively. See the DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS section for information on interactive column resizing. The default value is `1`. This option is only relevant if the value of the `-resizablecolumns` widget configuration option is true.
  `-selectbackground color`
    Specifies the background color to use when displaying the contents of a cell in the given column while the cell is selected.
  `-selectforeground color`
    Specifies the foreground color to use when displaying the contents of a cell in the given column while the cell is selected.
  `-showarrow boolean`
    Specifies whether the `sortbycolumn` command with the given column index as first argument and the `sortbycolumnlist` command having the given column index as element of its first argument should place an arrow indicating the sort order into the column's label. The default value is `1`. This option is only relevant if the value of the `-showarrow` widget configuration option is true.
  `-showlinenumbers boolean`
    Specifies whether the given column should display the line numbers (starting with 1 and ending with the number of the non-hidden rows). The default value is `0`.

    The following details assume that the given column's `-showlinenumbers` option was set to true: Associating the line numbers with the non-hidden rows takes place automatically whenever items are inserted, deleted, updated, moved, or sorted. For increased efficiency, this is in most cases done at idle time. For example, if several items are inserted into or deleted from the tablelist widget, then the necessary renumbering of the non-hidden rows will be performed as an idle callback, the next time the event loop is entered and there are no events to process. The line numbers will override any previous contents of the column's cells. They are, per default, displayed without leading zeros, but this (and the display format in general) can be changed with the aid of the `-formatcommand` column configuration option.

    The `sortbycolumn` and `sortbycolumnlist` subcommands as well as the `tablelist::sortByColumn` and `tablelist::addToSortColumns` commands check the column indices passed to them as arguments and don't perform any sorting by those columns that have been configured to display the line numbers (see the corresponding descriptions for details).

  `-sortcommand command`
    This option is only relevant if the value of the `-sortmode` option for the given column is `command`. It specifies a command to be used for the comparison of the column's elements when invoking the `sortbycolumn` command with the given column index as first argument or the `sortbycolumnlist` command having the given column index as element of its first argument. To compare two elements during the `sortbycolumn` or `sortbycolumnlist` operation, `command` is automatically concatenated with the two elements and the resulting script is evaluated. The script should return an integer less than, equal to, or greater than zero if the first element is to be considered less than, equal to, or greater than the second, respectively.
  `-sortmode mode`
    Specifies how to compare the column's elements when invoking the `sortbycolumn` command with the given column index as first argument or the `sortbycolumnlist` command having the given column index as element of its first argument. `mode` may have any of the following values:

    `ascii` | Use string comparison with Unicode code-point collation order (the name is for backward-compatibility reasons). This is the default.
    `asciinocase` | This is the same as `ascii`, except that comparisons are handled in a case-insensitive manner.
    `command` | Use the command specified by the `-sortcommand` column configuration option to compare the column's elements.
    `dictionary` | Use dictionary-style comparison. This is the same as `ascii`, except: (a) case is ignored except as a tie-breaker; (b) if two strings contain embedded numbers, the numbers compare as integers, not characters. For example, `bigBoy` sorts between `bigbang` and `bigboy`, and `x10y` sorts between `x9y` and `x11y`.
    `integer` | Convert the elements to integers and use integer comparison.
    `real` | Convert the elements to floating-point values and use floating-point comparison.

  `-stretchable boolean`
    Specifies whether the column is to be stretched in order to fill the tablelist window if necessary. The value of this option is tied to that of the `-stretch` option for the tablelist widget; changes in either will automatically be reflected in the other.
  `-text list`
    Specifies a list of strings to be displayed in the cells of the given column, i.e., updates the elements contained in the column. If the tablelist's `state` is `disabled` then this option will be ignored.
  `-title title`
    Specifies the text to be displayed in the column's header. This option is tied to the `title` element corresponding to the given column in the list specifying the value of the `-columns` option for the tablelist widget; changes in either will automatically be reflected in the other.
  `-width width`
    `width` must be a number. A positive value specifies the column's width in average-size characters of the widget's font. If `width` is negative, its absolute value is interpreted as a column width in pixels. Finally, a value of zero specifies that the column's width is to be made just large enough to hold all the elements in the column, including its header (but no larger than the maximum width indicated by the `-maxwidth` column configuration option). This option is tied to the `width` element corresponding to the given column in the list specifying the value of the `-columns` option for the tablelist widget; changes in either will automatically be reflected in the other.
  `-wrap boolean`
    Specifies whether to display those elements of the given column that don't fit into their cells in word-wrapped multi-line rather than snipped form. The default value is `0`. If the specified column has static width and the value of this option is true then elements of the column that are too long to be displayed in a single line will be broken up into several lines. The same applies to the individual lines of the multi-line elements (i.e., elements containing newline characters): they will also be wrapped if necessary, thus giving rise to additional line breaks. In both cases, the line breaks are chosen at word boundaries wherever possible, and they are only used for the external representation of the strings contained in the given column, without affecting the internal contents of the cells.
  The `-background`, `-font`, `-foreground`, `-selectbackground`, and `-selectforeground` column configuration options override the options of the same names set at widget level (but not the ones set at cell or row level) if the specified value is not an empty string. See the COLORS AND FONTS section for further details on these options.
ROW CONFIGURATION OPTIONS
  The following options are currently supported by the `rowcget`, `rowconfigure`, `configrowlist`, and `configrows` commands:
  `-background color` or `-bg color`
    Specifies the normal background color to use when displaying the contents of the row.
  `-font font`
    Specifies the font to use when displaying the contents of the row.
  `-foreground color` or `-fg color`
    Specifies the normal foreground color to use when displaying the contents of the row.
  `-hide boolean`
    Specifies whether to hide the row when displaying the widget or exporting its selection. The default value is `0`. After toggling the hidden state of a row, the `<<TablelistRowHiddenStateChanged>>` virtual event is generated.

    For technical reasons (the use of the `-elide` option for a text widget tag), this option is not supported for Tk versions earlier than 8.3.

    CAUTION: Tk versions 8.3 - 8.4.12 had a bug that caused a segmentation fault if the whole content of a text widget was elided. This bug was also present in Tk 8.5.a1 - 8.5.a3. When using one of these earlier Tk versions, this bug will produce a crash if all the rows of a tablelist widget are hidden. It is your responsibility to avoid such situations when using a Tk version having this bug!

  `-name name`
    Specifies a name associated with the row. While the numerical index of a row might change by inserting, deleting, or moving rows, or by sorting the items, its name remains constant and can be used as a safe alternative row index (see the ROW INDICES section for details). Similarly, it can also be used as the first component of a cell index of the form `row,col`, as described in the CELL INDICES section. To avoid ambiguities, row names should be different from any other forms of row indices (like numbers, full keys, `active`, `anchor`, `end`, `top`, `bottom`, or any of their abbreviations). The default value is an empty string.
  `-selectable boolean`
    Specifies whether the elements displayed in the given row can be selected. The default value is `1`. If the value `0` was given then any attempt to select the item contained in this row with the aid of the `selection set` widget command or any of its elements by using the `cellselection set` command will be silently ignored; moreover, an existing old (cell) selection is removed from the row.
  `-selectbackground color`
    Specifies the background color to use when displaying the contents of a cell in the given row while the cell is selected.
  `-selectforeground color`
    Specifies the foreground color to use when displaying the contents of a cell in the given row while the cell is selected.
  `-text list`
    Specifies a list of strings to be displayed in the cells of the given row, i.e., updates the item contained in the row. If the tablelist's `state` is `disabled` then this option will be ignored.
  The `-background`, `-font`, `-foreground`, `-selectbackground`, and `-selectforeground` row configuration options override the options of the same names set at column or widget level (but not the ones set at cell level) if the specified value is not an empty string. See the COLORS AND FONTS section for further details on these options.
CELL CONFIGURATION OPTIONS
  The following options are currently supported by the `cellcget`, `cellconfigure`, `configcelllist`, and `configcells` commands:
  `-background color` or `-bg color`
    Specifies the normal background color to use when displaying the contents of the cell.
  `-editable boolean`
    Specifies whether the contents of the cell can be edited interactively. The default value is `0`. This option overrides the one of the same name for the column containing the given cell.
  `-editwindow name`
    Specifies the type of the temporary embedded widget to be used for interactive editing of the cell's contents. The default value is `entry`. This option overrides the one of the same name for the column containing the given cell, and may have the same values as its column-related counterpart.
  `-font font`
    Specifies the font to use when displaying the contents of the cell.
  `-foreground color` or `-fg color`
    Specifies the normal foreground color to use when displaying the contents of the cell.
  `-image image`
    Specifies the name of the Tk image to be displayed in the cell. `image` must be the result of an invocation of the `image create` command, or an empty string, specifying that no image is to be displayed. If the column containing the cell is right-aligned then the image will be displayed to the right of the cell's text, otherwise to its left. The text and the image are separated from each other by a gap of 4 pixels. If for the same cell the `-window` option was specified with a nonempty value then it overrides the `-image` option. If the tablelist's `state` is `disabled` then this option will be ignored.

    To display an image in a cell, Tablelist makes use of an embedded label widget (which is created on demand). This requires more memory than inserting the image directly into the tablelist's body, but has the main advantage of making it possible to adjust the width of the label containing the widget to fit into its column. This has the visual effect of cutting off part of the image from its right side. To make sure that images with transparent background will be displayed correctly, the background color of the label widgets containing the embedded images is automatically updated whenever necessary.

  `-selectbackground color`
    Specifies the background color to use when displaying the contents of the cell while it is selected.
  `-selectforeground color`
    Specifies the foreground color to use when displaying the contents of the cell while it is selected.
  `-stretchwindow boolean`
    Specifies whether the width of the window embedded into the cell shall be adapted dynamically to the width of the cell's column if the latter is non-zero (i.e., static). The default value is `0`. If the value of this option is true and the column was specified with a non-zero width or was resized interactively, then the width of the embedded window (if any) will be adjusted automatically so the window fills the whole horizontal space belonging to that column (except the left and right margins). Please note that in this case the cell's text will remain hidden. On the other hand, if the column is of dynamic width then this option will be ignored and both the cell's text and its embedded window (if any) will be displayed as usual. The easiest way to avoid this discrepancy is to set the cell's text to an empty string or make sure that the column's elements are always displayed as empty strings, by using the `-formatcommand` column configuration option.
  `-text text`
    Specifies the string to be displayed in the given cell, i.e., updates the element contained in the cell. If the tablelist's `state` is `disabled` then this option will be ignored.
  `-window command`
    Specifies a Tcl command creating the window to be embedded into the cell. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, as well as the path name of the embedded window to be created, and the resulting script is evaluated in the global scope. `command` may also be an empty string, specifying that no embedded window is to be displayed. If the column containing the cell is right-aligned then the window will be displayed to the right of the cell's text, otherwise to its left. The text and the window are separated from each other by a gap of 4 pixels. If this option was specified with a nonempty value then it overrides the `-image` cell configuration option. If the tablelist's `state` is `disabled` then this option will be ignored.

    REMARK: There are several situations where the embedded window will be destroyed and later recreated by invoking the script mentioned above. For example, when changing the value of some of the tablelist widget or column configuration options, sorting the items, or moving a row or a column, the widget's contents will be redisplayed, which makes it necessary to recreate the embedded windows. This operation won't preserve the changes made on the embedded windows after their creation. For this reason, you should avoid any changes on embedded windows outside their creation scripts.

  `-windowdestroy command`
    Specifies a Tcl command to be invoked when a window embedded into the cell is destroyed. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, as well as the path name of the embedded window, and the resulting script is evaluated in the global scope. This option provides an easy-to-use alternative to binding a script to the embedded window's `<Destroy>` event from within its creation script, specified as the value of the `-window` cell configuration option.
  `-windowupdate command`
    Specifies a Tcl command responsible for adapting the background and foreground colors of a window embedded into the cell to the current background and foreground colors of the cell itself. The current cell colors depend on whether the tablelist widget's `state` is `normal` or `disabled`, whether the cell is selected, and whether its row is displayed with the colors specified by the `-stripebackground` and `-stripeforeground` options. The command is automatically concatenated with the name of the tablelist widget, the cell's row and column indices, the path name of the embedded window, the option name `-background` and the cell's current background color, as well as the option name `-foreground` and the cell's current foreground color. The resulting script is then evaluated in the global scope. The specified command can use the colors passed to it as arguments to set the corresponding colors of the embedded window to the same values.

    For example, if the embedded window is a text widget and you want for its background and foreground colors to be automatically adapted to the cell's current background and foreground colors, then you can achieve this by setting the `-windowupdate` cell configuration option to `updateWindow`, where the latter is the procedure implemented as follows:

    >     proc updateWindow {tbl row col w args} {
    >         eval [list $w configure] $args
    >     }

    With Tcl/Tk 8.5 or above, you can use the more compact form

    >     proc updateWindow {tbl row col w args} {
    >         $w configure {*}$args
    >     }

    In this example, `args` is a list of the form

    >     -background backgroundColor -foreground foregroundColor

  The `-background`, `-font`, `-foreground`, `-selectbackground`, and `-selectforeground` cell configuration options override the options of the same names set at row, column, or widget level if the specified value is not an empty string. See the COLORS AND FONTS section for further details on these options.
USING A TABLELIST AS MULTI-COLUMN TREE WIDGET
  When using a tablelist widget to display a tree hierarchy, there are a few rules to follow:
  1. Do not use the the widget's `-listvariable` option, or at least do not add new items to the variable specified as its value, because adding new items to that list will result in inserting those list elements into the widget without respecting the tree's internal structure.
  2. Make sure that the column specified by the `-treecolumn` option is left-aligned so the tree structure can be displayed as expected.
  3. Use the `insertchild(ren)` or `insertchildlist` subcommand rather than `insert` or `insertlist` for inserting new items into the widget.
INTERACTIVE CELL EDITING
  Whether or not the contents of a cell of a tablelist widget can be edited interactively, depends on the `-editable` option on both cell and column level. If the cell-level option was set explicitly then its value determines the editability of the cell's contents. Otherwise the value of the column-level option is used to decide whether the cell can be edited interactively. From this rule it follows that you can enable interactive cell editing for a whole column by setting its `-editable` option to true. To exclude some of the column's cells from interactive editing, set their `-editable` option to false.
  The interactive cell editing is started by the `editcell` subcommand, which is invoked implicitly by clicking with the left mouse button into an editable cell (see the `-editselectedonly` option for details) or using keyboard navigation to move from one editable cell into another. If the selection type is `cell` and the location cursor is in an editable cell, then the interactive editing of the active element can also be started by pressing `Return` or `KP_Enter`. Per default, the `editcell` subcommand creates a temporary entry widget and embeds it into the cell whose index was passed to it as argument. You can, however, use the `-editwindow` column or cell configuration option to specify another widget instead of an entry, like a Tk core text, spinbox, checkbutton, or menubutton widget, or a tile entry, spinbox, combobox, checkbutton, or menubutton, or one of the 18 currently supported widgets from the packages BWidget, Iwidgets, combobox (by Bryan Oakley), and Mentry (or Mentry_tile). Before specifying a widget from one of these library packages as the value of the `-editwindow` column or cell configuration option, you must register it for interactive cell editing by invoking the corresponding `tablelist::add*` command. The above-mentioned Tk core and tile widgets are automatically registered for cell editing.
  In the simplest case, the text automatically inserted into the temporary embedded widget is the same as the text displayed in the cell, which in turn can be the cell's contents or the string obtained from the latter by using the `-formatcommand` option of the cell's column. However, if the value of the `-editstartcommand` configuration option is a nonempty string, then the text displayed in the cell is passed to that command as its last argument (following the tablelist's path name as well as the cell's row and column indices), the resulting script is evaluated in the global scope, and the return value becomes the edit window's contents. From within this script you can invoke the `cancelediting` subcommand, which destroys the temporary embedded widget and cancels the editing of its contents. The main goal of this script is, however, to enable you to define validations for the editing process. This can be done either with the aid of the options for entry validation, supported by Tk versions 8.3 and higher (see the entry reference page), or by using the widget callback package Wcb, available for Tk versions 8.0 and higher. The Iwidgets package (available for Tk versions 8.0 or higher) provides its own validation facilities, which can equally be used if the edit window is a widget belonging to that extension. In either case, you will need the path name of the temporary embedded widget or that of its entry or entry-like component; use the `editwinpath` and `entrypath` subcommands to get these path names. Another purpose of the command indicated by the `-editstartcommand` option is to enable you to prepare the edit window in various other ways. For example, if the latter is a combobox widget then you can set its `-editable` option to false or (for a tile combobox) set its state to `readonly`, and you will have to populate its listbox component. In the same script, you can change some of the embedded widget's visual attributes (like its background, selection background, or selection foreground color). (Notice that this can also be done with the aid of the Tk option database.)
  The editing of the text inserted into the edit window uses the widget-specific bindings for mouse and keyboard events, with a few extensions and changes, as described in the DEFAULT BINDINGS FOR INTERACTIVE CELL EDITING section. For example, in entry or entry-like components of the edit window, `Control-i` inserts a tab, `Control-j` inserts a newline, and if the edit window is a text widget then `Return` and `KP_Enter` insert a newline character, too. `Tab` and `Shift-Tab` are used for navigation between the editable cells, just like `Alt-Left`, `Alt-Right`, `Alt-Up`, `Alt-Down`, `Alt-Prior`, `Alt-Next`, `Alt-Home`, and `Alt-End` (as well as `Control-Home` and `Control-End`, except in the case of a text widget). On Mac OS Classic and Mac OS X Aqua the `Command` key is used instead of `Alt`. The editing can be aborted with the `Escape` key (or by invoking the `cancelediting` subcommand) and terminated normally with `Return` or `KP_Enter` (together with `Control` for a text widget). The bindings for the keys used for normal termination of the editing just invoke the `finishediting` subcommand; the latter can also be called explicitly to terminate the editing programmatically. Normal termination is also triggered by clicking with the left mouse button anywhere in the tablelist's body, outside the cell just being edited, or moving into another editable cell by using keyboard navigation.
  When normal termination of the editing process occurs, the Tcl command associated with the tablelist widget compares the edit window's final contents to its original one. If they are equal then the embedded widget is destroyed and the cell's original value is restored. If the two strings are different and the value of the `-editendcommand` configuration option is a nonempty string, then the edit window's final text is passed to that command as its last argument (following the tablelist's path name as well as the cell's row and column indices), the resulting script is evaluated in the global scope, and the return value becomes the cell's new internal contents after destroying the temporary embedded widget. The main goal of this script is to enable you to do a final validation of the edit window's contents. From within this script you can invoke the `rejectinput` subcommand, which prevents the script's return value from becoming the cell's new contents; this subcommand also prevents the destruction of the temporary embedded widget. Another purpose of the command indicated by the `-editendcommand` option is to convert the edit window's text to the cell's new internal contents, which is necessary if, due to the `-formatcommand` column configuration option, the cell's internal value is different from its external representation. See the description of the `-forceeditendcommand` option for more about the invocation of the command mentioned above.
ROW INDICES
  Many of the widget commands for tablelist widgets take one or more row indices as arguments. A row index specifies a particular item of the tablelist, in any of the following ways:

  `number` | Specifies the item as a numerical index, where `0` corresponds to the first item in the tablelist.
  `knumber` | Specifies the item by its full key, composed of the letter `k` and the sequence number associated with the item. You can use the `getkeys` widget command to get this sequence number, or the `getfullkeys` widget command to retrieve the full key. In addition, the `insert`, `insertlist`, `insertchildren`, and `insertchildlist` subcommands return the list of full keys associated with the items just inserted.
  `active` | Indicates the item containing the element that has the location cursor. Depending on the selection type, this item as a whole or just its element having the location cursor will be displayed according to the value of the `-activestyle` configuration option when the tablelist has the keyboard focus. This item is specified with the `activate` widget command or as the row containing the element specified with the `activatecell` widget command.
  `anchor` | Indicates the anchor point for the row selection, which is set with the `selection anchor` widget command, or the row containing the anchor point for the cell selection, which is set with the `cellselection anchor` widget command.
  `end` | Indicates the end of the tablelist. For most commands this refers to the last item in the tablelist, but for a few commands such as `index`, `insert`, and `insertlist`, as well as for the target of the `move` command it refers to the item just after the last one.
  `top` | Indicates the topmost item visible in the tablelist window.
  `bottom` | Indicates the bottommost item visible in the tablelist window.
  `@x,y` | Indicates the item that covers the point in the tablelist window specified by `x` and `y` (in pixel coordinates). If no item covers that point, then the closest item to that point is used. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).
  `name` | Specifies the row by the value of its `-name` configuration option. `name` must be different from all the above row indices, and should be unique (if several rows have the same name then this value is considered to indicate the first matching row).

  In the widget command descriptions below, arguments named `index`, `first`, `last`, `sourceIndex`, and `targetIndex` always contain row indices in one of the above forms.

NODE INDICES
  Many of the widget commands for tablelist widgets take a node index as argument. A node index is either the word `root`, denoting the invisible root node of a tablelist used as a tree widget, or a regular row index in one of the above forms, specifying a particular item of the tablelist.

  In the widget command descriptions below, arguments named `nodeIndex`, `parentNodeIndex`, and `targetParentNodeIndex` always contain node indices.

COLUMN INDICES
  Many of the widget commands for tablelist widgets take one or more column indices as arguments. A column index specifies a particular column of the tablelist, in any of the following ways:

  `number` | Specifies the column as a numerical index, where `0` corresponds to the first column in the tablelist.
  `active` | Indicates the column containing the element that has the location cursor. If the selection type is `cell` then this element will be displayed according to the value of the `-activestyle` configuration option when the tablelist has the keyboard focus. This element is specified with the `activatecell` widget command.
  `anchor` | Indicates the column containing the anchor point for the cell selection, which is set with the `cellselection anchor` widget command.
  `end` | Indicates the last column of the tablelist, except for the commands `insertcolumns` and `insertcolumnlist`, as well as for the target of the `movecolumn` command, in which cases it refers to the column just after the last one.
  `left` | Indicates the leftmost column visible in the tablelist window.
  `right` | Indicates the rightmost column visible in the tablelist window.
  `@x,y` | Indicates the column that covers the point in the tablelist window specified by `x` and `y` (in pixel coordinates). If no column covers that point, then the closest column to that point is used. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).
  `name` | Specifies the column by the value of its `-name` configuration option. `name` must be different from all the above column indices, and should be unique (if several columns have the same name then this value is considered to indicate the first matching column).

  In the widget command descriptions below, arguments named `columnIndex`, `firstColumn`, `lastColumn`, `sourceColumn`, and `targetColumn` always contain column indices in one of the above forms.

CELL INDICES
  Many of the widget commands for tablelist widgets take one or more cell indices as arguments. A cell index specifies a particular cell of the tablelist, in any of the following ways:

  `row,col` | Indicates the cell having the row index `row` and column index `col`. `row` may be a number, a full key (of the form `knumber`), `active`, `anchor`, `end` (where the latter indicates the last row in the tablelist), `top`, `bottom`, or a row name. `col` may be a number, `active`, `anchor`, `end`, `left`, `right`, or a column name.
  `active` | Indicates the element that has the location cursor. If the selection type is `cell` then this element will be displayed according to the value of the `-activestyle` configuration option when the tablelist has the keyboard focus. This element is specified with the `activatecell` widget command.
  `anchor` | Indicates the anchor point for the cell selection, which is set with the `cellselection anchor` widget command.
  `end` | Indicates the last cell in the last row of the tablelist.
  `@x,y` | Indicates the cell that covers the point in the tablelist window specified by `x` and `y` (in pixel coordinates). If no cell covers that point, then the closest cell to that point is used. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).

  In the widget command descriptions below, arguments named `cellIndex`, `firstCell`, and `lastCell` always contain cell indices in one of the above forms.

WIDGET COMMAND
  The `tablelist::tablelist` command creates a new Tcl command whose name is `pathName`. This command may be used to invoke various operations on the widget. It has the following general form:

  >     pathName option ?arg arg ...?

  `option` and the `arg`s determine the exact behavior of the command. The following commands are possible for tablelist widgets:
  `pathName activate index`
    Sets the active item to the one indicated by `index` if the tablelist's `state` is not `disabled`. If `index` is outside the range of items in the tablelist or it refers to a hidden item then the closest non-hidden item is activated. The active item is drawn as specified by the `-activestyle` configuration option when the widget has the input focus and the selection type is `row`. Its index may be retrieved with the index `active`. Returns an empty string.
  `pathName activatecell cellIndex`
    Sets the active element to the one indicated by `cellIndex` if the tablelist's `state` is not `disabled`. If `cellIndex` is outside the range of elements in the tablelist or it refers to a hidden element, then the closest non-hidden element is activated. The active element is drawn as specified by the `-activestyle` configuration option when the widget has the input focus and the selection type is `cell`. Its index may be retrieved with the cell index `active`. Returns an empty string.
  `pathName applysorting itemList`
    Sorts the elements of `itemList` according to the parameters of the most recent `sort`, `sortbycolumn`, or `sortbycolumnlist` invocation and returns a new list in sorted order. The `itemList` argument is supposed to be a well-formed list of lists, where the length of each sublist is expected to be no less than the number of columns of the tablelist widget. If the items haven't been sorted at all, or the sort information was reset by invoking `resetsortinfo`, then no sorting takes place and the return value will be identical to `itemList`.

    REMARK: This subcommand is usually invoked from within the command specified as the value of the `-expandcommand` configuration option, for a tablelist row whose children have not yet been inserted into the widget. The most efficient way to insert the child items in the correct order is to add them to a list, sort this list via `applysorting`, and then insert the items of the sorted list by invoking the `insertchildlist` subcommand.

  `pathName attrib ?name? ?value name value ...?`
    Queries or modifies the attributes of the widget. If no `name` is specified, the command returns a list of pairs, each of which contains the name and the value of an attribute for `pathName`. If `name` is specified with no `value`, then the command returns the value of the one named attribute, or an empty string if no corresponding value exists (you can use the `hasattrib` subcommand to distinguish this case from the one that the value of an existing attribute is an empty string). If one or more `name`-`value` pairs are specified, then the command sets the given widget attribute(s) to the given value(s); in this case the return value is an empty string. `name` may be an arbitrary string.
  `pathName bbox index`
    Returns a list of four numbers describing the bounding box of the row given by `index`. The first two elements of the list give the x and y coordinates of the upper-left corner of the screen area covered by the row (specified in pixels relative to the widget) and the last two elements give the width and height of the area, in pixels. If no part of the row given by `index` is visible on the screen, or if `index` refers to a non-existent row, then the result is an empty string; if the row is partially visible, the result gives the full area of the row, including any parts that are not visible.
  `pathName bodypath`
    Returns the path name of the body component of the widget.
  `pathName bodytag`
    Returns the name of a binding tag whose name depends on the path name of the tablelist widget and which is associated with the tablelist's body, the separators, as well as the message and label widgets used for displaying multi-line elements and images, respectively. This binding tag precedes the tag `TablelistBody` in the list of binding tags of the tablelist descendants mentioned above, and is designed to be used when defining individual binding scripts for tablelist widgets. The main advantage of using this tag instead of the path name of the tablelist's body is that it enables you to write event handling scripts that are valid not only for the tablelist's body but also for the separators, multi-line cells, and embedded images.
  `pathName cancelediting`
    This subcommand cancels the interactive editing of the contents of the cell whose index was passed to the `editcell` subcommand, destroys the temporary widget embedded into the cell, and restores the original cell contents. This command enables you to cancel the interactive cell editing from within the Tcl command specified by the `-editstartcommand` configuration option if that pre-edit callback encounters an error when preparing the text to be inserted into the edit window. The command is also invoked implicitly by pressing the `Escape` key when a cell is being edited. The return value is an empty string. Immediately before returning this value, the command generates the virtual event `<<TablelistCellRestored>>`. If no cell was being edited when the command was invoked then an empty string is returned without generating a virtual event.
  `pathName cellattrib cellIndex ?name? ?value name value ...?`
    Queries or modifies the attributes of the cell given by `cellIndex`. If no `name` is specified, the command returns a list of pairs, each of which contains the name and the value of an attribute for the cell. If `name` is specified with no `value`, then the command returns the value of the one named cell attribute, or an empty string if no corresponding value exists (you can use the `hascellattrib` subcommand to distinguish this case from the one that the value of an existing cell attribute is an empty string). If one or more `name`-`value` pairs are specified, then the command sets the given cell attribute(s) to the given value(s); in this case the return value is an empty string. `name` may be an arbitrary string.
  `pathName cellcget cellIndex option`
    Returns the current value of the cell configuration option given by `option` for the cell specified by `cellIndex`. `option` may have any of the values accepted by the `cellconfigure` command.
  `pathName cellconfigure cellIndex ?option? ?value option value ...?`
    Queries or modifies the configuration options of the cell given by `cellIndex`. If no `option` is specified, the command returns a list describing all of the available options for the cell (see `Tk_ConfigureInfo` for information on the format of this list). If `option` is specified with no `value`, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no `option` is specified). If one or more `option`-`value` pairs are specified, then the command modifies the given cell option(s) to have the given value(s); in this case the return value is an empty string. `option` may have any of the values described in the CELL CONFIGURATION OPTIONS section.
  `pathName cellindex cellIndex`
    Returns the canonical cell index value that corresponds to `cellIndex`, in the form `row,col`, where `row` and `col` are integers.
  `pathName cellselection option args`
    This command is used to adjust the cell selection within a tablelist widget. It has several forms, depending on `option`:
    `pathName cellselection anchor cellIndex`
      Sets the cell selection anchor to the element given by `cellIndex`. If `cellIndex` refers to a nonexistent or hidden element, then the closest non-hidden element is used. The cell selection anchor is the end of the cell selection that is fixed while dragging out a cell selection with the mouse if the selection type is `cell`. The cell index `anchor` may be used to refer to the anchor element.
    `pathName cellselection clear firstCell lastCell`
    `pathName cellselection clear cellIndexList`
      If any of the elements between `firstCell` and `lastCell` (inclusive) or corresponding to the cell indices specified by the list `cellIndexList` are selected, they are deselected. The selection state is not changed for elements outside the range given in the first form of the command or different from those specified by the cell index list given in its second form.
    `pathName cellselection includes cellIndex`
      Returns `1` if the element indicated by `cellIndex` is currently selected, `0` if it isn't.
    `pathName cellselection set firstCell lastCell`
    `pathName cellselection set cellIndexList`
      Selects all of the selectable elements in the range between `firstCell` and `lastCell`, inclusive, or corresponding to the indices specified by the list `cellIndexList`, without affecting the selection state of any other elements. An element is viewed as selectable if and only if the value of the `-selectable` option of the row containing it is true.
    If the tablelist's `state` is `disabled` and `option` is different from `includes` then the command just returns an empty string, without performing any of the above actions.
  `pathName cget option`
    Returns the current value of the configuration option given by `option`, which may have any of the values accepted by the `tablelist::tablelist` command.
  `pathName childcount nodeIndex`
    Returns the number of children of the tree node indicated by `nodeIndex`. If this argument is specified as `root` then the return value will be the number of top-level items of the tablelist widget.
  `pathName childindex index`
    Returns the numerical index of the row given by `index` in the list of children of its parent node.
  `pathName childkeys nodeIndex`
    Returns the list of full keys of the children of the tree node indicated by `nodeIndex`. If this argument is specified as `root` then the return value will be the list of full keys of the top-level items contained in the tablelist widget.
  `pathName collapse index ?-fully|-partly?`
    This subcommand collapses the specified row of a tablelist used as a tree widget, i.e., hides all its descendants. The optional argument `-fully` (which is the default) indicates that the command will be performed recursively, i.e., all of the descendants of the node specified by `index` will be collapsed, so that a subsequent invocation of the non-recursive version of the `expand(all)` subcommand will only display the row's children but no further descendants of it. The `-partly` option (which is used by the default bindings) restricts the operation to just one hierarchy level, implying that by a subsequent invocation of the non-recursive version of the `expand(all)` subcommand exactly the same descendants will be displayed again that were visible prior to collapsing the row.

    Before hiding the descendants of a row, the command specified as the value of the `-collapsecommand` option (if any) is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope.

    For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this subcommand is not supported for Tk versions earlier than 8.3.

  `pathName collapseall ?-fully|-partly?`
    This subcommand collapses all top-level rows of a tablelist used as a tree widget, i.e., hides all their descendants. The optional argument `-fully` (which is the default) indicates that the command will be performed recursively, i.e., all of the descendants of the top-level nodes will be collapsed, so that a subsequent invocation of the non-recursive version of the `expandall` subcommand will only display ther children but no further descendants of them. The `-partly` option restricts the operation to just one hierarchy level, implying that by a subsequent invocation of the non-recursive version of the `expandall` subcommand exactly the same items will be displayed again that were visible prior to collapsing the top-level ones.

    Before hiding the descendants of a row, the command specified as the value of the `-collapsecommand` option (if any) is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope.

    For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this subcommand is not supported for Tk versions earlier than 8.3.

  `pathName columnattrib columnIndex ?name? ?value name value ...?`
    Queries or modifies the attributes of the column given by `columnIndex`. If no `name` is specified, the command returns a list of pairs, each of which contains the name and the value of an attribute for the column. If `name` is specified with no `value`, then the command returns the value of the one named column attribute, or an empty string if no corresponding value exists (you can use the `hascolumnattrib` subcommand to distinguish this case from the one that the value of an existing column attribute is an empty string). If one or more `name`-`value` pairs are specified, then the command sets the given column attribute(s) to the given value(s); in this case the return value is an empty string. `name` may be an arbitrary string.
  `pathName columncget columnIndex option`
    Returns the current value of the column configuration option given by `option` for the column specified by `columnIndex`. `option` may have any of the values accepted by the `columnconfigure` command.
  `pathName columnconfigure columnIndex ?option? ?value option value ...?`
    Queries or modifies the configuration options of the column given by `columnIndex`. If no `option` is specified, the command returns a list describing all of the available options for the column (see `Tk_ConfigureInfo` for information on the format of this list). If `option` is specified with no `value`, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no `option` is specified). If one or more `option`-`value` pairs are specified, then the command modifies the given column option(s) to have the given value(s); in this case the return value is an empty string. `option` may have any of the values described in the COLUMN CONFIGURATION OPTIONS section.
  `pathName columncount`
    Returns the number of columns in the tablelist widget.
  `pathName columnindex columnIndex`
    Returns the integer column index value that corresponds to `columnIndex`.
  `pathName columnwidth columnIndex ?-requested|-stretched|-total?`
    Returns the current width in pixels of the column specified by `columnIndex`. If the optional argument is `-requested` (which is the default) then the return value is the number of pixels corresponding to the column width specified by the `-columns` widget or `-width` column configuration option (possibly overridden by interactive column resizing); if the column width was specified as `0` (and was not changed by interactive column resizing) then the return value is the actual number of pixels corresponding to the widest non-hidden element of the column, including its header. With the `-stretched` option, the command returns the column width obtained by increasing the value described above by the number of additional pixels that might have been added to the requested column width by a stretch operation (see the `-stretch` widget and `-stretchable` column configuration options). Finally, if the optional argument is `-total` then the return value is the stretched column width increased by the number of pixels corresponding to the left and right margins within the column; this value equals the width of the header label if the tablelist widget is mapped.
  `pathName configcelllist cellConfigSpecList`
    For each cell index, option, and value specified by the list `cellConfigSpecList`, the command modifies the given option of the given cell to have the given value. The argument `cellConfigSpecList` must be a list of the form

    >     cellIndex option value cellIndex option value ...

    where each `option` may have any of the values described in the CELL CONFIGURATION OPTIONS section. The return value is an empty string.

    This command has the same effect as

    >     eval [list pathName configcells] cellConfigSpecList

    but it is more efficient and easier to use.

  `pathName configcells ?cellIndex option value cellIndex option value ...?`
    For each `cellIndex`, `option`, and `value`, the command modifies the given option of the given cell to have the given value. Each `option` may have any of the values described in the CELL CONFIGURATION OPTIONS section. The return value is an empty string.
  `pathName configcolumnlist columnConfigSpecList`
    For each column index, option, and value specified by the list `columnConfigSpecList`, the command modifies the given option of the given column to have the given value. The argument `columnConfigSpecList` must be a list of the form

    >     columnIndex option value columnIndex option value ...

    where each `option` may have any of the values described in the COLUMN CONFIGURATION OPTIONS section. The return value is an empty string.

    This command has the same effect as

    >     eval [list pathName configcolumns] columnConfigSpecList

    but it is more efficient and easier to use.

  `pathName configcolumns ?columnIndex option value columnIndex option value ...?`
    For each `columnIndex`, `option`, and `value`, the command modifies the given option of the given column to have the given value. Each `option` may have any of the values described in the COLUMN CONFIGURATION OPTIONS section. The return value is an empty string.
  `pathName configrowlist rowConfigSpecList`
    For each row index, option, and value specified by the list `rowConfigSpecList`, the command modifies the given option of the given row to have the given value. The argument `rowConfigSpecList` must be a list of the form

    >     index option value index option value ...

    where each `option` may have any of the values described in the ROW CONFIGURATION OPTIONS section. The return value is an empty string.

    This command has the same effect as

    >     eval [list pathName configrows] rowConfigSpecList

    but it is more efficient and easier to use.

  `pathName configrows ?index option value index option value ...?`
    For each `index`, `option`, and `value`, the command modifies the given option of the given row to have the given value. Each `option` may have any of the values described in the ROW CONFIGURATION OPTIONS section. The return value is an empty string.
  `pathName configure ?option? ?value option value ...?`
    Queries or modifies the configuration options of the widget. If no `option` is specified, the command returns a list describing all of the available options for `pathName` (see `Tk_ConfigureInfo` for information on the format of this list). If `option` is specified with no `value`, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no `option` is specified). If one or more `option`-`value` pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the return value is an empty string. `option` may have any of the values accepted by the `tablelist::tablelist` command.
  `pathName containing y`
    Given a y-coordinate within the tablelist window, this command returns the index of the tablelist item containing that y-coordinate. If no corresponding item is found then the return value is `-1`. The coordinate `y` is expected to be relative to the tablelist window itself (not its body component).
  `pathName containingcell x y`
    Given an x- and a y-coordinate within the tablelist window, this command returns the index of the tablelist cell containing the point having these coordinates. If no corresponding cell is found then the row or column component (or both) of the return value is `-1`. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).
  `pathName containingcolumn x`
    Given an x-coordinate within the tablelist window, this command returns the index of the tablelist column containing that x-coordinate. If no corresponding column is found then the return value is `-1`. The coordinate `x` is expected to be relative to the tablelist window itself (not its body component).
  `pathName cornerlabelpath`
    Returns the path name of the label widget contained in the corner frame (see the `cornerpath` subcommand. When using Tablelist_tile, the return value will be a ttk::label widget of the same style as the header labels. The global visual options set for the header labels are automatically applied to this (ttk::)label widget, too.
  `pathName cornerpath`
    Returns the path name of a frame widget that is a sibling of the tablelist and is automatically created and destroyed together with the latter's header. This frame is called the corner frame, because it is designed to be shown to the right of the tablelist widget's top-right corner when managing the vertical scrollbar on Mac OS X Aqua (see below). The corner frame contains a label or ttk::label widget, depending on whether the package Tablelist or Tablelist_tile is being used (see the `cornerlabelpath` subcommand). Whenever the height of the tablelist's header changes, the height of the corner frame as well as that of the above-mentioned (ttk::)label widget is updated accordingly.

    This subcommand enables you to manage the vertical scrollbar (if any) to appear below the tablelist widget's header, thus respecting the native look & feel on Mac OS X Aqua. As shown in the following example, it is recommended to always create a scrolled tablelist along with the scrollbar(s) as children of a (ttk::)frame widget:

    >     # Add some entries to the Tk option database
    >     set winSys [tk windowingsystem]
    >     if {[string compare $winSys "x11"] != 0} {
    >         option add *ScrollArea.borderWidth                  1
    >         option add *ScrollArea.relief                       sunken
    >         option add *ScrollArea.Tablelist.borderWidth        0
    >         option add *ScrollArea.Tablelist.highlightThickness 0
    >     }

    >     . . .

    >     # Create the tablelist and the scrollbars as
    >     # children of a frame of class ScrollArea
    >     set frm [(ttk::)frame ... -class ScrollArea]
    >     set tbl $frm.tbl
    >     set vsb $frm.vsb
    >     set hsb $frm.hsb
    >     tablelist::tablelist $tbl ... \
    >         -xscrollcommand [list $hsb set] -yscrollcommand [list $vsb set]
    >     scrollbar $vsb -orient vertical   -command [list $tbl yview]
    >     scrollbar $hsb -orient horizontal -command [list $tbl xview]

    >     . . .

    >     # Manage the widgets within the frame
    >     grid $tbl -row 0 -rowspan 2 -column 0 -sticky news
    >     if {[string compare $winSys "aqua"] == 0} {
    >         grid [$tbl cornerpath] -row 0 -column 1 -sticky ew
    >         grid $vsb              -row 1 -column 1 -sticky ns
    >     } else {
    >         grid $vsb -row 0 -rowspan 2 -column 1 -sticky ns
    >     }
    >     grid $hsb -row 2 -column 0 -sticky ew
    >     grid rowconfigure    $frm 1 -weight 1
    >     grid columnconfigure $frm 0 -weight 1

    >     # Manage the frame
    >     pack $frm -expand yes -fill both

  `pathName curcellselection`
    Returns a list containing the canonical indices (of the form `row,col`, where `row` and `col` are numbers) of all of the elements in the tablelist that are currently selected. If there are no such elements in the tablelist then an empty string is returned.
  `pathName curselection`
    Returns a list containing the numerical indices of all of the items in the tablelist that contain at least one selected element. If there are no such items in the tablelist then an empty string is returned.
  `pathName delete first last`
  `pathName delete indexList`
    Deletes one or more items of the tablelist if its `state` is not `disabled`. In the first form of the command, `first` and `last` are indices specifying the first and last items in the range to delete. The command's second form accepts a list `indexList` of indices specifying the items to be deleted. In both cases, all descendants of the specified items will be deleted, too. The return value is an empty string.
  `pathName deletecolumns firstColumn lastColumn`
  `pathName deletecolumns columnIndexList`
    Deletes one or more columns of the tablelist if its `state` is not `disabled`. In the first form of the command, `firstColumn` and `lastColumn` are indices specifying the first and last columns in the range to delete. The command's second form accepts a list `columnIndexList` of indices specifying the columns to be deleted. Returns an empty string.
  `pathName depth nodeIndex`
    Returns the number of steps from the tree node indicated by `nodeIndex` to the `root` node. The latter's depth is 0, that of the top-level rows is 1, and so on.
  `pathName descendantcount nodeIndex`
    Returns the number of descendants of the tree node indicated by `nodeIndex`. If this argument is specified as `root` then the return value will be the number of items of the tablelist widget.
  `pathName editcell cellIndex`
    Starts the interactive editing of the cell's contents if the tablelist's `state` is not `disabled`, the cell's row and column are not hidden, and the cell is editable. Returns an empty string. See the INTERACTIVE CELL EDITING section for details on editablity and on the editing process.
  `pathName editwintag`
    Returns the name of a binding tag whose name depends on the path name of the tablelist widget and which is associated with some of the components of the temporary embedded widget used for interactive cell editing. These components depend on the edit window: the widget itself in case of a Tk or tile checkbutton or menubutton; the edit window's entry children in case of a mentry widget; the only entry or entry-like component of the edit window in all other cases (see also the `entrypath` subcommand). This binding tag precedes the tag `TablelistEdit` in the list of binding tags of the edit window components mentioned above, and is designed to be used when defining individual binding scripts for controlling the interactive cell editing.

    For example, the following command will replace the standard behavior of the `Return` key during cell editing in the tablelist widget `.tbl` with that of the `Tab` key:

    >     bind [.tbl editwintag] <Return> "[bind TablelistEdit <Tab>]; break"

  `pathName editwinpath`
    Returns the path name of the temporary embedded widget used for interactive cell editing, created by the `editcell` subcommand. If no cell is currently being edited then the return value is an empty string. This subcommand enables you to access the edit window from within the commands specified by the `-editstartcommand` and `-editendcommand` configuration options.
  `pathName entrypath`
    Returns the path name of the entry or entry-like component of the temporary embedded widget used for interactive cell editing, created by the `editcell` subcommand. If no cell is currently being edited or the editing is taking place with the aid of a Tk or tile checkbutton, Tk or tile menubutton, or mentry widget, then the return value is an empty string; otherwise it is the path name of a Tk or tile entry, Tk text, Tk or tile spinbox, or BWidget Entry widget, which can be the edit window itself or one of its descendants. This subcommand enables you to access the entry or entry-like component of the temporary embedded widget from within the commands specified by the `-editstartcommand` and `-editendcommand` configuration options.
  `pathName expand index ?-fully|-partly?`
    This subcommand expands the specified row of a tablelist used as a tree widget, i.e., makes all its children visible. The optional argument `-fully` (which is the default) indicates that the command will be performed recursively, i.e., all of the descendants of the node specified by `index` will be displayed. The `-partly` option (which is used by the default bindings) restricts the operation to just one hierarchy level, indicating that only the children of the specified node will be displayed, without changing the expanded/collapsed state of the child nodes.

    Before displaying the children of a row, the command specified as the value of the `-expandcommand` option (if any) is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope. This enables you to insert a tree node's children on demand, just before expanding it.

    For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this subcommand is not supported for Tk versions earlier than 8.3.

  `pathName expandall ?-fully|-partly?`
    This subcommand expands all top-level rows of a tablelist used as a tree widget, i.e., makes all their children visible. The optional argument `-fully` (which is the default) indicates that the command will be performed recursively, i.e., all of the descendants of the top-level nodes will be displayed. The `-partly` option restricts the operation to just one hierarchy level, indicating that only the children of the top-level nodes will be displayed, without changing the expanded/collapsed state of the child nodes.

    Before displaying the children of a row, the command specified as the value of the `-expandcommand` option (if any) is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope. This enables you to insert a tree node's children on demand, just before expanding it.

    For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this subcommand is not supported for Tk versions earlier than 8.3.

  `pathName expandedkeys`
    Returns the list of full keys of the expanded items.
  `pathName fillcolumn columnIndex text`
    Sets all the elements of the specified column to the value `text`.
  `pathName finishediting`
    This subcommand attempts to terminate the interactive editing of the contents of the cell whose index was passed to the `editcell` subcommand by destroying the temporary widget embedded into the cell and updating the cell's contents. The exact steps involved are as follows: First, the widget's final text is compared to its original one. If they are equal then the edit window is destroyed and the cell's original contents are restored. If the two strings are different and the value of the `-editendcommand` configuration option is a nonempty string, then the widget's final text is passed to that command as its last argument (following the tablelist's path name as well as the cell's row and column indices), the resulting script is evaluated in the global scope, and the return value becomes the cell's new contents after destroying the edit window. However, if from within this script the `rejectinput` subcommand was invoked then the cell's value is not changed and the embedded widget remains displayed in the cell; in this case the command returns the boolean value `0`. In all the other cases, the return value is `1`. Immediately before returning the value `1`, the command generates the virtual event `<<TablelistCellUpdated>>`. If no cell was being edited when the command was invoked then the same value `1` is returned but no virtual event is generated.

    This subcommand is called implicitly by pressing `Return` or `KP_Enter` (together with `Control` if the edit window is a text widget) when editing a cell, or by clicking with the left mouse button anywhere in the tablelist's body, outside the cell just being edited, or moving into another editable cell by using keyboard navigation.

    REMARK: There are also situations where an explicit invocation of this subcommand is needed, in order to make sure that the cell just being edited gets updated with the text entered by the user. For example, if a tablelist widget is part of a dialog used for editing some data, then the binding script associated with the button designed to accept the data should call this subcommand, because otherwise, if the button is pressed during interactive cell editing then the text entered into the edit window will get lost.

  `pathName formatinfo`
    This command is designed to be invoked from within a Tcl command specified as the value of the `-formatcommand` column configuration option. It returns a three-element list containing information about the tablelist cell whose content is being formatted with the aid of that command. The first element of the list is the full key (of the form `knumber`) associated with the item containing the tablelist element that is being formatted. The second and third elements of the list are the cell's row and column indices.

    REMARK: This subcommand is needed in cases where the result of the formatting should depend on the cell's row. To be able to use it, specify the value of the `-formatcommand` column configuration option as `[list formatCommand pathName]`, like in the following example:

    >     .tbl columnconfigure 1 -formatcommand [list formatValue .tbl]

    >     proc formatValue {tbl val} {
    >         # Get information about the cell whose content is being formatted
    >         foreach {key row col} [$tbl formatinfo] {}

    >         # Return a string depending on $val and $row (or $key)
    >         . . .
    >     }

  `pathName get first last`
  `pathName get indexList`
    The first form of the command returns a list whose elements are all of the tablelist items (i.e., row contents) between `first` and `last`, inclusive. The value returned by the second form depends on the number of elements in the list `indexList`: if the latter contains exactly one index then the return value is the tablelist item indicated by that index (or an empty string if the index refers to a non-existent item); otherwise the command returns the list of all of the tablelist items corresponding to the indices specified by `indexList`.
  `pathName getcells firstCell lastCell`
  `pathName getcells cellIndexList`
    The first form of the command returns a list whose elements are all of the tablelist elements (i.e., cell contents) between `firstCell` and `lastCell`, inclusive. The value returned by the second form depends on the number of elements in the list `cellIndexList`: if the latter contains exactly one cell index then the return value is the tablelist element indicated by that cell index; otherwise the command returns the list of all of the tablelist elements corresponding to the cell indices specified by `cellIndexList`.
  `pathName getcolumns firstColumn lastColumn`
  `pathName getcolumns columnIndexList`
    The first form of the command returns a list whose elements are lists themselves, where each of the sublists corresponds to exactly one column between `firstColumn` and `lastColumn`, inclusive, and consists of all of the tablelist elements contained in that column. The value returned by the second form depends on the number of elements in the list `columnIndexList`: if the latter contains exactly one column index then the return value is a list consisting of all of the tablelist elements contained in the column indicated by that column index; otherwise the command returns a list whose elements are lists themselves, where each of the sublists corresponds to exactly one column index in `columnIndexList` and consists of all of the tablelist elements contained in that column.
  `pathName getformatted first last`
  `pathName getformatted indexList`
    The first form of the command returns a list whose elements are all of the formatted tablelist items (i.e., formatted row contents) between `first` and `last`, inclusive. The value returned by the second form depends on the number of elements in the list `indexList`: if the latter contains exactly one index then the return value is the formatted tablelist item indicated by that index (or an empty string if the index refers to a non-existent item); otherwise the command returns the list of all of the formatted tablelist items corresponding to the indices specified by `indexList`.
  `pathName getformattedcells firstCell lastCell`
  `pathName getformattedcells cellIndexList`
    The first form of the command returns a list whose elements are all of the formatted tablelist elements (i.e., formatted cell contents) between `firstCell` and `lastCell`, inclusive. The value returned by the second form depends on the number of elements in the list `cellIndexList`: if the latter contains exactly one cell index then the return value is the formatted tablelist element indicated by that cell index; otherwise the command returns the list of all of the formatted tablelist elements corresponding to the cell indices specified by `cellIndexList`.
  `pathName getformattedcolumns firstColumn lastColumn`
  `pathName getformattedcolumns columnIndexList`
    The first form of the command returns a list whose elements are lists themselves, where each of the sublists corresponds to exactly one column between `firstColumn` and `lastColumn`, inclusive, and consists of all of the formatted tablelist elements contained in that column. The value returned by the second form depends on the number of elements in the list `columnIndexList`: if the latter contains exactly one column index then the return value is a list consisting of all of the formatted tablelist elements contained in the column indicated by that column index; otherwise the command returns a list whose elements are lists themselves, where each of the sublists corresponds to exactly one column index in `columnIndexList` and consists of all of the formatted tablelist elements contained in that column.
  `pathName getfullkeys first last`
  `pathName getfullkeys indexList`
    The first form of the command returns a list whose elements are all of the full keys associated with the tablelist items between `first` and `last`, inclusive. The value returned by the second form depends on the number of elements in the list `indexList`: if the latter contains exactly one index then the return value is the full key associated with the tablelist item indicated by that index (or an empty string if the index refers to a non-existent item); otherwise the command returns the list of all of the full keys associated with the tablelist items corresponding to the indices specified by `indexList`.

    Each item of a tablelist widget has a unique sequence number that remains unchanged until the item is deleted, thus acting as a key that uniquely identifies the item even if the latter's position (i.e., numerical row index) changes. This command provides read-only access to the full keys obtained by prepending the letter `k` to these internal item IDs.

  `pathName getkeys first last`
  `pathName getkeys indexList`
    The first form of the command returns a list whose elements are all of the sequence numbers associated with the tablelist items between `first` and `last`, inclusive. The value returned by the second form depends on the number of elements in the list `indexList`: if the latter contains exactly one index then the return value is the sequence number associated with the tablelist item indicated by that index (or an empty string if the index refers to a non-existent item); otherwise the command returns the list of all of the sequence numbers associated with the tablelist items corresponding to the indices specified by `indexList`.

    Each item of a tablelist widget has a unique sequence number that remains unchanged until the item is deleted, thus acting as a key that uniquely identifies the item even if the latter's position (i.e., numerical row index) changes. This command provides read-only access to these internal item IDs.

  `pathName hasattrib name`
    Returns `1` if the attribute `name` exists and `0` otherwise.
  `pathName hascellattrib cellIndex name`
    Returns `1` if the attribute `name` for the cell given by `cellIndex` exists and `0` otherwise.
  `pathName hascolumnattrib columnIndex name`
    Returns `1` if the attribute `name` for the column given by `columnIndex` exists and `0` otherwise.
  `pathName hasrowattrib index name`
    Returns `1` if the attribute `name` for the row given by `index` exists and `0` otherwise.
  `pathName imagelabelpath cellIndex`
    Returns the path name of the label widget containing the image embedded into the cell given by `cellIndex`, as specified with the `-image` option of the `cellconfigure` subcommand. If no image is currently embedded into the cell then the return value is an empty string.
  `pathName index index`
    Returns the integer row index value that corresponds to `index`. If `index` is `end` then the return value is the number of items in the tablelist (not the index of the last item).
  `pathName insert index ?item item ...?`
    Inserts zero or more new items in the widget's internal list just before the item given by `index` if the tablelist's `state` is not `disabled`. If `index` equals the number of items or is specified as `end` then the new items are added to the end of the widget's list. Tabulator characters are displayed as `\t` (i.e., a backslash followed by a `t`) but are inserted unchanged into the internal list. Newline characters will force line breaks, i.e., will give rise to multi-line elements (which are displayed in embedded message widgets, created on demand). The return value is the list of full keys associated with the items just inserted.

    REMARK: This subcommand is not suitable for inserting items into a tablelist designed for displaying a tree hierarchy. For such tablelist widgets use the `insertchildren` or `insertchildlist` subcommand.

  `pathName insertchildlist parentNodeIndex childIndex itemList`
    Inserts the items of the list `itemList` in the widget's internal list of children of the node specified by `parentNodeIndex` just before the item given by `childIndex` if the tablelist's `state` is not `disabled`. `childIndex` must be a number or `end`; if it equals the number of children of the node given by `parentNodeIndex` or is specified as `end` then the new items are added to the end of the parent's list of children. Tabulator characters are displayed as `\t` (i.e., a backslash followed by a `t`) but are inserted unchanged into the internal list. Newline characters will force line breaks, i.e., will give rise to multi-line elements (which are displayed in embedded message widgets, created on demand). The return value is the list of full keys associated with the items just inserted.

    This command has the same effect as

    >     eval [list pathName insertchildren parentNodeIndex childIndex] itemList

    but it is more efficient and easier to use.

    For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this subcommand is not supported for Tk versions earlier than 8.3.

    REMARK: You can achieve a quite significant speadup by using this subcommand to insert a whole list of items rather than using multiple invocations of `insertchildren`.

  `pathName insertchildren parentNodeIndex childIndex ?item item ...?`
    Inserts zero or more new items in the widget's internal list of children of the node specified by `parentNodeIndex` just before the item given by `childIndex` if the tablelist's `state` is not `disabled`. `childIndex` must be a number or `end`; if it equals the number of children of the node given by `parentNodeIndex` or is specified as `end` then the new items are added to the end of the parent's list of children. Tabulator characters are displayed as `\t` (i.e., a backslash followed by a `t`) but are inserted unchanged into the internal list. Newline characters will force line breaks, i.e., will give rise to multi-line elements (which are displayed in embedded message widgets, created on demand). The return value is the list of full keys associated with the items just inserted.

    For technical reasons (the use of the `-elide` text widget tag option for collapsing a row), this subcommand is not supported for Tk versions earlier than 8.3.

    REMARK: It is explicitly allowed to abbreviate the name `insertchildren` as `insertchild`. This comes in handy when using this subcommand to insert just one child item.

  `pathName insertcolumnlist columnIndex columnList`
    Inserts the columns specified by the list `columnList` just before the column given by `columnIndex` if the tablelist's `state` is not `disabled`. If `columnIndex` equals the number of columns or is specified as `end` then the new columns are added to the end of the column list. The argument `columnList` must be a list containing the width, title, and optional alignment specifications for the new columns, in the same form as in the case of the `-columns` configuration option. The return value is an empty string. The elements of the new columns are initially empty strings; the easiest way to change these values is to use the `fillcolumn` subcommand or the `-text` column configuration option.

    This command has the same effect as

    >     eval [list pathName insertcolumns columnIndex] columnList

    but it is more efficient and easier to use.

  `pathName insertcolumns columnIndex ?width title ?alignment? width title ?alignment? ...?`
    Inserts zero or more new columns just before the column given by `columnIndex` if the tablelist's `state` is not `disabled`. If `columnIndex` equals the number of columns or is specified as `end` then the new columns are added to the end of the column list. The arguments following the column index have the same meanings as in the case of the `-columns` configuration option. The return value is an empty string. The elements of the new columns are initially empty strings; the easiest way to change these values is to use the `fillcolumn` subcommand or the `-text` column configuration option.
  `pathName insertlist index itemList`
    Inserts the items of the list `itemList` in the widget's internal list just before the item given by `index` if the tablelist's `state` is not `disabled`. If `index` equals the number of items or is specified as `end` then the new items are added to the end of the widget's list. Tabulator characters are displayed as `\t` (i.e., a backslash followed by a `t`) but are inserted unchanged into the internal list. Newline characters will force line breaks, i.e., will give rise to multi-line elements (which are displayed in embedded message widgets, created on demand). The return value is the list of full keys associated with the items just inserted.

    This command has the same effect as

    >     eval [list pathName insert index] itemList

    but it is more efficient and easier to use.

    REMARK 1: You can achieve a quite significant speadup by using this subcommand to insert a whole list of items rather than using multiple invocations of `insert`.

    REMARK 2: This subcommand is not suitable for inserting items into a tablelist designed for displaying a tree hierarchy. For such tablelist widgets use the `insertchildlist` or `insertchildren` subcommand.

  `pathName iselemsnipped cellIndex fullTextName`
    Returns the value `1` if the text displayed in the cell specified by `cellIndex` is snipped and `0` otherwise. In both cases, the full (unsnipped) cell text is stored in the variable having the name given by `fullTextName`; this full text can be the cell's contents or the string obtained from the latter by using the `-formatcommand` option of the cell's column. The most common invocation of this command occurs within the procedure specified as the value of the `-tooltipaddcommand` configuration option.
  `pathName isexpanded index`
    Returns the value `1` if the item indicated by `index` is expanded and `0` otherwise.
  `pathName istitlesnipped columnIndex fullTextName`
    Returns the value `1` if the text displayed in the header label specified by `columnIndex` is snipped and `0` otherwise. In both cases, the full (unsnipped) label text is stored in the variable having the name given by `fullTextName`. The most common invocation of this command occurs within the procedure specified as the value of the `-tooltipaddcommand` configuration option.
  `pathName itemlistvar`
    Returns the name of a variable used by Tablelist to hold the widget's internal list. The recommended way to use this variable is to create a link to it with the aid of the `upvar` command, like in the following example:

    >     upvar #0 [.tbl itemlistvar] itemList

    In this example, the value of the variable `itemList` will be the internal list of the tablelist widget `.tbl`. Each element of the widget's internal list corresponds to one item, and it is in turn a list whose elements correspond to the elements of that item, except that it has one additional element, holding the item's full key.

    REMARK: The `itemlistvar` command provides an efficient way for accessing this internal list, instead of retrieving the items with the `get` subcommand or using the `-listvariable` option (these methods consume significantly more memory). It can be useful in situations where the elements of a tablelist widget are to be accessed for creating text files, HTML output, XML data, database commands, etc. This should, however, be a strictly readonly access; otherwise the results will be unpredictable!

  `pathName labelpath columnIndex`
    Returns the path name of the header label corresponding to the column indicated by `columnIndex`.
  `pathName labels`
    Returns a list containing the path names of all header labels of the widget.
  `pathName labeltag`
    Returns the name of a binding tag whose name depends on the path name of the tablelist widget and which is associated with the header labels as well as with the additional widgets placed by Tablelist into the latters for displaying header images and sort arrows. This binding tag is designed to be used when defining non-default binding scripts for the header labels. From within such event handling scripts you can retrieve the column number and the tablelist widget's path name with the aid of the helper commands `tablelist::getTablelistColumn` and `tablelist::getTablelistPath`.
  `pathName move sourceIndex targetIndex`
  `pathName move sourceIndex targetParentNodeIndex targetChildIndex`
    The first form of the command moves the item indicated by `sourceIndex` just before the one given by `targetIndex` if the tablelist's `state` is not `disabled`. If `targetIndex` equals the nunber of items or is specified as `end` then the source item is moved after the last one. The item specified by `targetIndex` must have the same parent as the one given by `sourceIndex`, or else it must be the item just below the last descendant of the source node's parent.

    The command's second form moves the item indicated by `sourceIndex` just before the node having the parent indicated by `targetParentNodeIndex` and the index `targetChildIndex` in the parent's list of children if the tablelist's `state` is not `disabled`. `targetChildIndex` must be a number or `end`; if it equals the number of children of the target parent node or is specified as `end` then the source item is moved after the target parent node's last child.

    Both forms of the command preserve the node hierarchy under the source item, by moving its descendants accordingly. The return value is an empty string.

  `pathName movecolumn sourceColumn targetColumn`
    Moves the column indicated by `sourceColumn` just before the one given by `targetColumn` if the tablelist's `state` is not `disabled`. If `targetColumn` equals the number of columns or is specified as `end` then the source column is moved after the last one. Returns an empty string.
  `pathName nearest y`
    Given a y-coordinate within the tablelist window, this command returns the index of the non-hidden tablelist item nearest to that y-coordinate. The coordinate `y` is expected to be relative to the tablelist window itself (not its body component).
  `pathName nearestcell x y`
    Given an x- and a y-coordinate within the tablelist window, this command returns the index of the non-hidden tablelist cell nearest to the point having these coordinates. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).
  `pathName nearestcolumn x`
    Given an x-coordinate within the tablelist window, this command returns the index of the non-hidden tablelist column nearest to that x-coordinate. The coordinate `x` is expected to be relative to the tablelist window itself (not its body component).
  `pathName noderow parentNodeIndex childIndex`
    Returns the numerical row index of the node having the parent indicated by `parentNodeIndex` and the index `childIndex` in the parent's list of children. `childIndex` must be a number or `end`; if it equals the number of children of the parent node or is specified as `end` then the return value will be the row index of the item following the parent node's last descendant.
  `pathName parentkey nodeIndex`
    Returns the full key of the parent of the tree node indicated by `nodeIndex`. If this argument is specified as `root` then the return value will be an empty string. If `nodeIndex` identifies a top-level item then the subcommand will return `root`. For all other items the return value will be a full key of the form `knumber`.
  `pathName refreshsorting ?parentNodeIndex?`
    Sorts the children of the tablelist node specified by `parentNodeIndex` according to the parameters of the most recent `sort`, `sortbycolumn`, or `sortbycolumnlist` invocation. If the items haven't been sorted at all, or the sort information was reset by invoking `resetsortinfo`, then no sorting takes place. The optional argument `parentNodeIndex` defaults to `root`, meaning that all the items are to be sorted per default. The return value is an empty string.
  `pathName rejectinput`
    If invoked from within the Tcl command specified by the `-editendcommand` configuration option, then this subcommand prevents the termination of the interactive editing of the contents of the cell whose index was passed to the `editcell` subcommand. It invokes the `seecell` subcommand to make sure the respective cell becomes visible (in case it was scrolled out of view), and sets the focus to the temporary widget embedded into the cell. This command enables you to reject the widget's text during the final validation of the string intended to become the new cell contents. The return value is an empty string.
  `pathName resetsortinfo`
    Resets the information about the sorting of the items. Subsequent invocations of `sortcolumn` and `sortorder` will return `-1` and an empty string, respectively. Similarly, subsequent invocations of `sortcolumnlist` and `sortorderlist` will return an empty string. This command also removes any existing up- or down-arrows displayed by an earlier invocation of `sortbycolumn` or `sortbycolumnlist`. The return value is an empty string.
  `pathName rowattrib index ?name? ?value name value ...?`
    Queries or modifies the attributes of the row given by `index`. If no `name` is specified, the command returns a list of pairs, each of which contains the name and the value of an attribute for the row. If `name` is specified with no `value`, then the command returns the value of the one named row attribute, or an empty string if no corresponding value exists (you can use the `hasrowattrib` subcommand to distinguish this case from the one that the value of an existing row attribute is an empty string). If one or more `name`-`value` pairs are specified, then the command sets the given row attribute(s) to the given value(s); in this case the return value is an empty string. `name` may be an arbitrary string.
  `pathName rowcget index option`
    Returns the current value of the row configuration option given by `option` for the row specified by `index`. `option` may have any of the values accepted by the `rowconfigure` command.
  `pathName rowconfigure index ?option? ?value option value ...?`
    Queries or modifies the configuration options of the row given by `index`. If no `option` is specified, the command returns a list describing all of the available options for the row (see `Tk_ConfigureInfo` for information on the format of this list). If `option` is specified with no `value`, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no `option` is specified). If one or more `option`-`value` pairs are specified, then the command modifies the given row option(s) to have the given value(s); in this case the return value is an empty string. `option` may have any of the values described in the ROW CONFIGURATION OPTIONS section.
  `pathName scan option args`
    This command is used to implement scanning on tablelist widgets. It has two forms, depending on `option`:
    `pathName scan mark x y`
      Records `x` and `y` and the current view in the tablelist window; used in conjunction with later `scan dragto` commands. Typically this command is associated with a mouse button press in the body component of the widget. It returns an empty string. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).
    `pathName scan dragto x y`
      This command computes the difference between its `x` and `y` arguments to the last `scan mark` command for the widget. It then adjusts the view (the vertical one only in the body component) by 10 times the difference in coordinates. This command is typically associated with mouse motion events in the body component of the widget, to produce the effect of dragging the table at high speed through the window. The return value is an empty string. The coordinates `x` and `y` are expected to be relative to the tablelist window itself (not its body component).
  `pathName searchcolumn columnIndex pattern ?options?`
    This subcommand searches the elements of the column given by `columnIndex` to see if one of them matches `pattern`. If a match is found, the row index of the first matching element is returned as result (unless the option `-all` is specified). If not, the return value is `-1`. One or more of the following options may be specified to control the search:

    `-all` | Changes the result to be the list of all matching row indices, which will be in numeric order (or in reverse numeric order when used with the `-backwards` option).
    `-backwards` | The search will proceed backward through the given column's elements.
    `-check command` | Specifies an additional condition to be fulfilled by the matching elements. If an element of the specified column matches the given pattern and command is a nonempty string, then the latter is automatically concatenated with the name of the tablelist widget, the element's row index, the numerical equivalent of `columnIndex`, as well as the element itself or its formatted version (depending on the presence of the `-formatted` option), the resulting script is evaluated in the global scope, and the return value (which must be a boolean) will determine whether the element in question will still be viewed as matching or not. The default command is an empty string. This option enables you to pass arbitrary additional matching criteria to the searching process.
    `-descend` | Search the elements of the specified column in all descendants of the tree node given by the `-parent` option. The elements will be visited in the order of their row indices (or in reverse order of their row indices when used with the `-backwards` option). The default is to restrict the search to the parent node's children only.
    `-exact` | The matching element(s) must be identical to the literal string `pattern`.
    `-formatted` | Examine the formatted versions of the elements rather than the internal cell values.
    `-glob` | Treat `pattern` as a glob-style pattern and match it against the elements using the same rules as the `string match` command.
    `-nocase` | Causes comparisons to be handled in a case-insensitive manner. Has no effect if combined with the `-numeric` option.
    `-not` | This option negates the sense of the match, returning the row index of the first non-matching element (or, in the presence of the `-all` option, the list of row indices of all non-matching elements) of the given column.
    `-numeric` | The elements are to be compared to `pattern` as integer or floating-point values, using the `==` comparison operator. This option is only meaningful when used with `-exact`.
    `-parent nodeIndex` | This option restricts the search to the children (or descendants, when used with `-descend`) of the tree node given by `nodeIndex`. The default parent is `root`.
    `-regexp` | Treat `pattern` as a regular expression and match it against the elements using the rules described in the `re_syntax` reference page.
    `-start index` | The elements of the specified column are to be searched (forwards or backwards) starting at the row given by `index`. This option makes it easy to provide incremental search.

    If all matching style options `-exact`, `-glob`, and `-regexp` are omitted then the matching style defaults to `-glob`. If more than one of them is specified, the last matching style given takes precedence.

    Before examining the children (or descendants, when used with the `-descend` option) of a row whose children have not been inserted yet, the command specified as the value of the `-populatecommand` option (if any) is automatically concatenated with the name of the tablelist widget and the row index, and the resulting script is evaluated in the global scope. This enables you to insert the children on demand, just before searching them for the specified pattern.

  `pathName see index`
    Adjusts the view in the tablelist so that the item given by `index` is visible. If the item is already visible then the command has no effect; if the item is near one edge of the window then the tablelist scrolls to bring the item into view at the edge; otherwise the tablelist scrolls to center the item.
  `pathName seecell cellIndex`
    Adjusts the view in the tablelist so that the cell given by `cellIndex` is visible. If the cell is already visible then the command has no effect; if the cell is near one edge of the window then the tablelist scrolls to bring the cell into view at the edge; otherwise the tablelist scrolls to center the cell. If the value of the `-titlecolumns` option is positive then the centering of the cell is only done vertically; the horizontal scrolling (which in this case is performed column-wise) will just bring the cell into view next to the title columns or at the right edge of the window.
  `pathName seecolumn columnIndex`
    Adjusts the view in the tablelist so that the column given by `columnIndex` is visible. If the column is already visible then the command has no effect; if the column is near one edge of the window then the tablelist scrolls horizontally to bring the column into view at the edge; otherwise the tablelist scrolls horizontally to center the column. If the value of the `-titlecolumns` option is positive then the horizontal scrolling (which in this case is performed column-wise) will just bring the column into view next to the title columns or at the right edge of the window.
  `pathName selection option args`
    This command is used to adjust the selection within a tablelist widget. It has several forms, depending on `option`:
    `pathName selection anchor index`
      Sets the selection anchor to the item given by `index`. If `index` refers to a nonexistent or hidden item, then the closest non-hidden item is used. The selection anchor is the end of the selection that is fixed while dragging out a selection with the mouse if the selection type is `row`. The index `anchor` may be used to refer to the anchor item.
    `pathName selection clear first last`
    `pathName selection clear indexList`
      If any of the items between `first` and `last` (inclusive) or corresponding to the indices specified by the list `indexList` contain at least one selected cell, they are deselected. The selection state is not changed for items outside the range given in the first form of the command or different from those specified by the index list given in its second form.
    `pathName selection includes index`
      Returns `1` if the item indicated by `index` contains at least one selected cell, `0` if it doesn't.
    `pathName selection set first last`
    `pathName selection set indexList`
      Selects all of the selectable items in the range between `first` and `last`, inclusive, or corresponding to the indices specified by the list `indexList`, without affecting the selection state of any other items.
    If the tablelist's `state` is `disabled` and `option` is different from `includes` then the command just returns an empty string, without performing any of the above actions.
  `pathName separatorpath ?columnIndex?`
    If the optional argument is not specified, then this command returns the path name of the special separator displayed to mark the end of the title columns if the value of the `-titlecolumns` option is positive and an empty string otherwise. If the optional argument is present, then the command returns the path name of the separator attached to the right edge of the header label indicated by `columnIndex` if the value of the `-showseparators` configuration option is true and an empty string otherwise.
  `pathName separators`
    Returns a list containing the path names of all column separators. If the value of the `-titlecolumns` option is positive then the first element of the list will be the path name of the special separator displayed to mark the end of the title columns. Whether the path names of the other separators are included in the list, depends on the value of the `-showseparators` configuration option.
  `pathName size`
    Returns the total number of items in the tablelist widget.
  `pathName sort ?-increasing|-decreasing?`
    Sorts the items in increasing or decreasing order, as specified by the optional argument. The default is `-increasing`. Uses the value of the `-sortcommand` widget configuration option as comparison command. `sort` also removes any existing up- or down-arrows displayed by an earlier invocation of `sortbycolumn` or `sortbycolumnlist`. After sorting the items, the command conditionally adjusts the vertical view as follows: (a) if interactive cell editing is in progress then the cell being edited is brought into view; (b) else, if exactly one item is selected then the view is shifted to bring that item into view; (c) else, if the tablelist's body is the most recent window to have the input focus among all the windows in the same top-level as the widget itself then the currently active item is brought into view.
  `pathName sortbycolumn columnIndex ?-increasing|-decreasing?`
    Sorts the items based on the elements of the column given by `columnIndex`, in increasing or decreasing order, as specified by the optional argument. The default is `-increasing`. The sorting process is controlled by the values of the `-sortmode` and `-sortcommand` options for the given column. If both the value of the `-showarrow` configuration option and that of the `-showarrow` option for the specified column are true then an up- or down-arrow indicating the sort order will be placed into the column's label. The shape of the arrow depends on the command's optional argument and on the value of the `-incrarrowtype` configuration option. If the label's text is right-aligned then the arrow will be displayed on the left side of the label, otherwise on its right side. After sorting the items, the vertical view is adjusted in the same way as in the case of the `sort` subcommand.

    The actions described above are only performed if the specified column's `-showlinenumbers` option hasn't been set to true.

  `pathName sortbycolumnlist columnIndexList ?sortOrderList?`
    Sorts the items based on the elements of the columns given by the `columnIndexList` argument, which must be a list of distinct column indices. Only those elements of this list are considered significant that identify columns whose `-showlinenumbers` option hasn't been set to true.

    The items are first sorted based on the column specified by the last significant element of `columnIndexList`, then based on the one given by the last but one significant element, and so on. The order of each sort operation is taken from the optional argument `sortOrderList`, whose elements must be (abbreviations of) `increasing` or `decreasing`. If this argument was not specified or contains less elements than `columnIndexList` then the missing sort orders are assumed to be `increasing`. Each sorting process is controlled by the values of the `-sortmode` and `-sortcommand` options for the respective column. If the column's index was specified among the first 9 significant elements of `columnIndexList` and both the value of the `-showarrow` configuration option and that of the `-showarrow` option for that column are true then an up- or down-arrow indicating the sort order will be placed into the column's label. The shape of the arrow depends on the respective sort order and on the value of the `-incrarrowtype` configuration option. If the label's text is right-aligned then the arrow will be displayed on the left side of the label, otherwise on its right side. If more than one sort arrows are to be displayed then the first 9 sort ranks (`1` for the first significant element of `columnIndexList`, `2` for the second one, and so on) will also be shown to the right of the arrows. After sorting the items, the vertical view is adjusted in the same way as in the case of the `sort` subcommand.

  `pathName sortcolumn`
    Returns the numerical index of the column by which the items were last sorted with the aid of the `sortbycolumn` or `sortbycolumnlist` command, or `-1` if they were last sorted with the `sort` command or haven't been sorted at all, or the sort information was reset by invoking `resetsortinfo`. If called from within the command specified as the value of the `-sortcommand` widget or column configuration option, then the return value of this subcommand refers to the sorting in progress rather than the most recent one.
  `pathName sortcolumnlist`
    Returns a list consisting of the numerical indices of the columns by which the items were last sorted with the aid of the `sortbycolumnlist` or `sortbycolumn` command (in the second case the list will contain exactly one element), or an empty string if they were last sorted with the `sort` command or haven't been sorted at all, or the sort information was reset by invoking `resetsortinfo`. If called from within the command specified as the value of the `-sortcommand` widget or column configuration option, then the return value of this subcommand refers to the sorting in progress rather than the most recent one.
  `pathName sortorder`
    Returns the sort order (as `increasing` or `decreasing`) from the last sorting performed by the `sort`, `sortbycolumn`, or `sortbycolumnlist` command, or an empty string if the items haven't been sorted at all, or the sort information was reset by invoking `resetsortinfo`. If called from within the command specified as the value of the `-sortcommand` widget or column configuration option, then the return value of this subcommand refers to the sorting in progress rather than the most recent one.
  `pathName sortorderlist`
    Returns a list consisting of the sort orders (as `increasing` or `decreasing`) from the last invocation of the `sortbycolumnlist` or `sortbycolumn` command (in the second case the list will contain exactly one element), or an empty string if the items were last sorted with the `sort` command or haven't been sorted at all, or the sort information was reset by invoking `resetsortinfo`. If called from within the command specified as the value of the `-sortcommand` widget or column configuration option, then the return value of this subcommand refers to the sorting in progress rather than the most recent one.
  `pathName togglecolumnhide firstColumn lastColumn`
  `pathName togglecolumnhide columnIndexList`
    Toggles the value of the `-hide` option for one or more columns of the tablelist widget. In the first form of the command, `firstColumn` and `lastColumn` are indices specifying the first and last columns in the range whose visibility is to be toggled. The command's second form accepts a list `columnIndexList` of indices specifying the columns whose visibility is to be toggled. Returns an empty string. After toggling the hidden state of the specified columns, the `<<TablelistColHiddenStateChanged>>` virtual event is generated. The main advantage of using this command instead of invoking `columnconfigure` for each of the specified columns is that it causes only one redisplay of the widget's contents, thus being significantly faster.
  `pathName togglerowhide first last`
  `pathName togglerowhide indexList`
    Toggles the value of the `-hide` option for one or more rows of the tablelist widget. In the first form of the command, `first` and `last` are indices specifying the first and last rows in the range whose visibility is to be toggled. The command's second form accepts a list `indexList` of indices specifying the rows whose visibility is to be toggled. Returns an empty string. After toggling the hidden state of the specified rows, the `<<TablelistRowHiddenStateChanged>>` virtual event is generated. Just like the `-hide` row configuration option, this subcommand is not supported for Tk versions earlier than 8.3.

    CAUTION: Tk versions 8.3 - 8.4.12 had a bug that caused a segmentation fault if the whole content of a text widget was elided. This bug was also present in Tk 8.5.a1 - 8.5.a3. When using one of these earlier Tk versions, this bug will produce a crash if all the rows of a tablelist widget are hidden. It is your responsibility to avoid such situations when using a Tk version having this bug!

  `pathName toplevelkey index`
    If the item identified by `index` is a top-level one then the subcommand returns the full key of that item. Otherwise the return value is the full key of the unique top-level item having the given item among its descendants.
  `pathName unsetattrib name`
    Unsets the attribute `name`. Returns an empty string.
  `pathName unsetcellattrib cellIndex name`
    Unsets the attribute `name` for the cell given by `cellIndex`. Returns an empty string.
  `pathName unsetcolumnattrib columnIndex name`
    Unsets the attribute `name` for the column given by `columnIndex`. Returns an empty string.
  `pathName unsetrowattrib index name`
    Unsets the attribute `name` for the row given by `index`. Returns an empty string.
  `pathName windowpath cellIndex`
    Returns the path name of the window contained in the cell given by `cellIndex`, created with the `-window` option of the `cellconfigure` subcommand. If no window is currently embedded into the cell then the return value is an empty string.
  `pathName xview args`
    This command is used to query and change the horizontal position of the information in the widget's window. It can take any of the following forms:
    `pathName xview`
      Returns a list containing two elements. Each element is a real fraction between `0` and `1`; together they describe the horizontal span that is visible in the window. For example, if the first element is `.2` and the second element is `.6`, 20% of the tablelist's scrollable text is off-screen to the left, the middle 40% is visible in the window, and 40% of the scrollable text is off-screen to the right. These are the same values passed to scrollbars via the `-xscrollcommand` option.
    `pathName xview units`
      If the value of the `-titlecolumns` option is positive then this command adjusts the view in the window so that the column whose offset from the end of the title column area equals `units` non-hidden columns is displayed next to the title columns. Otherwise the command adjusts the view in the window so that the character position given by `units` is displayed at the left edge of the window. Character positions are defined by the width of the character `0`.
    `pathName xview moveto fraction`
      Adjusts the view in the window so that `fraction` of the total width of the scrollable tablelist text is off-screen to the left. `fraction` must be a fraction between `0` and `1`.
    `pathName xview scroll number what`
      This command shifts the view in the window left or right according to `number` and `what`. `number` must be an integer. `what` must be either `units` or `pages` or an abbreviation of one of these. If `what` is `units`, the view adjusts left or right by `number` non-hidden columns or character units (the width of the `0` character) on the display, depending on the value of the `-titlecolumns` option; if `what` is `pages` then the view adjusts by `number` screenfuls. If `number` is negative then columns or characters farther to the left become visible; if it is positive then columns or characters farther to the right become visible.
  `pathName yview args`
    This command is used to query and change the vertical position of the text in the window of the widget's body component. It can take any of the following forms:
    `pathName yview`
      Returns a list containing two elements, both of which are real fractions between `0` and `1`. The first element gives the position of the non-hidden tablelist item at the top of the window, relative to the tablelist as a whole (`0.5` means it is halfway through the tablelist, for example). The second element gives the position of the non-hidden tablelist item just after the last one in the window, relative to the tablelist as a whole. These are the same values passed to scrollbars via the `-yscrollcommand` option.
    `pathName yview units`
      Adjusts the view in the window so that the item whose offset equals `units` non-hidden rows is displayed at the top of the window.
    `pathName yview moveto fraction`
      Adjusts the view in the window so that the non-hidden item given by `fraction` appears at the top of the window. `fraction` is a fraction between `0` and `1`; `0` indicates the first non-hidden item in the tablelist, `0.33` indicates the non-hidden item one-third the way through the tablelist, and so on.
    `pathName yview scroll number what`
      This command shifts the view in the window up or down according to `number` and `what`. `number` must be an integer. `what` must be either `units` or `pages` or an abbreviation of one of these. If `what` is `units`, the view adjusts up or down by `number` non-hidden rows; if it is `pages` then the view adjusts by `number` screenfuls. If `number` is negative then earlier items become visible; if it is positive then later items become visible.
DEFAULT AND INDIVIDUAL BINDINGS FOR THE TABLELIST BODY
  The body component of a tablelist is implemented as a text widget whose binding tag `Text` is replaced with a new binding tag called `TablelistBody`. The latter has all the events of the `Listbox` widget class, and several of its binding scripts are obtained from those of `Listbox` by replacing the event fields `%W`, `%x`, and `%y` with the path name of the tablelist widget and the x and y coordinates relative to the latter. These values are assigned to the help variables `tablelist::W`, `tablelist::x`, and `tablelist::y` by invoking the helper command `tablelist::convEventFields` as follows:

  >     foreach {tablelist::W tablelist::x tablelist::y} \
  >         [tablelist::convEventFields %W %x %y] {}

  This conversion of the event fields is necessary because the Tcl command associated with a tablelist expects any coordinates relative to the widget itself, not its body component. It makes use of help variables from the `tablelist` namespace in order to avoid any conflicts with global variables.

  Several of the events have no `%x` and `%y` fields; in this case another helper command `tablelist::getTablelistPath` is used to set the help variable `tablelist::W` to the path name of the tablelist widget:

  >     set tablelist::W [tablelist::getTablelistPath %W]

  The binding tag `TablelistBody` replaces the class name (`Frame` or `TSeparator`) of the separator widgets, too. It also replaces the binding tag `Message` of the message widgets used to display multi-line elements, as well as the binding tag `Label` of the label widgets used to display embedded images. This makes sure that the default handling of the mouse events on the column separators, multi-line cells, and embedded images is the same as in the rest of the tablelist's body.

  When defining individual bindings for tablelist widgets, the same conversion of the event fields is needed as for the default bindings. For example, the binding script below for the tablelist widget `.tbl` prints the index of the cell where mouse button 1 was clicked:

  >     bind [.tbl bodytag] <Button-1> {
  >         foreach {tablelist::W tablelist::x tablelist::y} \
  >             [tablelist::convEventFields %W %x %y] {}
  >         puts "clicked on cell [.tbl containingcell $tablelist::x $tablelist::y]"
  >     }

  By associating the script with the binding tag returned by the `bodytag` subcommand instead of just with the path name of the tablelist's body we make sure to have the same event handling for the separators, multi-line cells, and embedded images as for the rest of the tablelist's body.

  The following improved version of the binding script above uses a procedure and thus eliminates the need for prefixing the converted variables with `"tablelist::"`:

  >     bind [.tbl bodytag] <Button-1> {printClickedCell %W %x %y}

  >     proc printClickedCell {w x y} {
  >         foreach {tbl x y} [tablelist::convEventFields $w $x $y] {}
  >         puts "clicked on cell [$tbl containingcell $x $y]"
  >     }

  The bindings associated with the binding tag `TablelistBody`, created automatically by the `tablelist::tablelist` command, ensure that the body component of a tablelist has the same default behavior as a listbox widget. If the selection type is `row` (which is the default) then everything described in the "DEFAULT BINDINGS" section of the listbox manual entry applies to the body component of a tablelist, too. The only difference is that the word "element" in that manual page has to be replaced with "item" when applying the description to the body of a tablelist widget.

  If the selection type is `cell` then everything described in the "DEFAULT BINDINGS" section of the listbox manual entry applies to the body component of a tablelist, too, with the following extensions and changes:

  1. If `Tab` or `Shift-Tab` is pressed, the location cursor (active element) moves to the next/previous element. If the selection mode is `browse` or `extended` then the new active element is also selected and all other elements are deselected. In `extended` mode the new active element becomes the selection anchor. Notice that these bindings replace the common inter-widget navigation via `Tab` and `Shift-Tab` with inter-cell navigation. Just like in the case of the text widget, `Control-Tab` and `Control-Shift-Tab` are intended to be used for widget-to-widget keyboard navigation. Unfortunately, this won't always work because some window managers intercept the latter key sequences and use them for their own purposes (like inter-workplace navigation). For this reason, Tablelist supports the additional key sequences `Meta-Tab` and `Meta-Shift-Tab` as replacements for `Control-Tab` and `Control-Shift-Tab`, respectively.
  2. If the `Left` or `Right` key is pressed, the location cursor (active element) moves to the previous/next element of the active row. If the selection mode is `browse` or `extended` then the new active element is also selected and all other elements are deselected. In `extended` mode the new active element becomes the selection anchor.
  3. In `extended` mode, `Shift-Left` and `Shift-Right` move the location cursor (active element) to the previous/next element of the active row and also extend the selection to that element in a fashion similar to dragging with mouse button 1.
  4. If the `Home` or `End` key is pressed, the location cursor (active element) moves to the first/last element of the active row, the new active element is selected, and all other elements are deselected.
  5. In `extended` mode, `Shift-Home` and `Shift-End` extend the selection to the first/last element of the active row. In `multiple` mode, `Shift-Home` and `Shift-End` move the location cursor to the first/last element of the active row.
  6. If the location cursor is in an editable cell then `Return` and `KP_Enter` start the interactive editing of the active element.

  Just like in the case of the listbox widget, any changes to the selection will automatically generate the virtual event `<<ListboxSelect>>`. Instead of this event (which is supported for compatibility reasons), the virtual event `<<TablelistSelect>>` can be used to be made aware of any changes to tablelist selection. Both events will be generated independently of the selection type.

  The following binding associated with the binding tag `TablelistBody` is only valid if the selection mode is `single` or `multiple`:

  > If mouse button 1 is clicked on an item and then dragged outside that item, and the value of the `-movablerows` configuration option is true, then the mouse cursor takes on the shape specified by the `-movecursor` option, indicating that the item in question is being moved to another position. The new item position (if any) is visualized with the aid of a gap placed before the target row or a bar placed inside the latter (depending on the current mouse position), indicating whether the source item would be moved before this row or become a child of it. This local drag & drop operation ends when mouse button 1 is released, and can be canceled by pressing the `Escape` key. In both cases, the mouse cursor is reset to its original value, specified by the `-cursor` configuration option. After releasing mouse button 1 in the presence of a valid target, the source item is moved before the target row or just before the latter's first child, and the virtual event `<<TablelistRowMoved>>` is generated.

  > Notice that, depending on the current mouse position during the local drag & drop, there can be a corresponding potential target row or not. For instance, a tree item cannot be moved before one of its descendants and not all items might be allowed to have children or to become top-level ones (example: in a file manager, regular file items cannot be parents of other items and should not be allowed to become top-level ones). To decide whether the row corresponding to the y-coordinate of the current mouse position represents a valid potential target, the Tablelist code first checks whether moving the source item before that row or making it a child of the latter is allowed from the point of view of the general tree structure. If this is the case and the move operation would change the source item's parent (and the Tk version is at least 8.3), then the command specified by the `-acceptchildcommand` configuration option is used to decide whether to allow to move the dragged item to the intended target position: If the value of this option is an empty string then the move operation is allowed (and the target position is visualized as described above). Otherwise the command is concatenated with the name of the tablelist widget, the node index of the would-be new parent node, and the row index of the dragged item, the resulting script is evaluated in the global scope, and the return value (which must be a boolean) will determine whether to allow to move the source item to the current mouse position.

  Finally, the following bindings associated with the binding tag `TablelistBody` apply to tablelists used as tree widgets:

  1. Pressing mouse button 1 over an expand/collapse control toggles the expanded/collapsed state of the corresponding row.
  2. If the current active row contains an expand/collapse control in collapsed state then the `Right`, `plus`, and `KP_Add` keys expand the corresponding row by invoking the non-recursive version of the `expand` subcommand.
  3. If the current active row contains an expand/collapse control in expanded state then the `Left`, `minus`, and `KP_Subtract` keys collapse the corresponding row by invoking the non-recursive version of the `collapse` subcommand.
DEFAULT AND INDIVIDUAL BINDINGS FOR THE HEADER LABELS
  The `tablelist::tablelist` command automatically creates the following bindings for the header labels:
  1. If the mouse pointer is on the right edge of a header label or within a few pixels of its right edge, and both the value of the `-resizablecolumns` configuration option and that of the `-resizable` option for the column corresponding to that label are true, then the mouse cursor takes on the shape specified by the `-resizecursor` option. By clicking mouse button 1 in this area and moving the mouse while its button 1 is down, the column corresponding to that label will be resized by the amount of the cursor motion. The interactive column resizing ends when mouse button 1 is released, and can be canceled by pressing the `Escape` key. In both cases, the mouse cursor is reset to its original value, specified by the `-cursor` configuration option. When the column resize operation is finished, the virtual event `<<TablelistColumnResized>>` is generated.
  2. If mouse button 1 is pressed over a header label but outside the resize area described above and then dragged outside the label, and the value of the `-movablecolumns` configuration option is true, then the mouse cursor takes on the shape specified by the `-movecolumncursor` option, indicating that the column in question is being moved to another position, visualized with the aid of a gap placed before the label of the target column. This operation ends when mouse button 1 is released, and can be canceled by pressing the `Escape` key when the mouse pointer is outside the label. In both cases, the mouse cursor is reset to its original value, specified by the `-cursor` configuration option. After releasing mouse button 1, the source column is moved before the one indicated by the gap mentioned above and the virtual event `<<TablelistColumnMoved>>` is generated.
  3. If mouse button 1 is pressed over a header label but outside the resize area described above and later released over the same label, and the command specified by the `-labelcommand` option is a nonempty string, then this command is concatenated with the name of the tablelist widget and the column index of the respective label, and the resulting script is evaluated in the global scope. If another nonempty label command was specified at column level by using the `columnconfigure` option of the Tcl command associated with the tablelist widget, then that column-specific command will be used instead of the global one. If mouse button 1 was pressed together with the `Shift` key then the widget- or column-specific command mentioned above will be replaced with the one specified by the `-labelcommand2` option at widget or column level.
  4. The Tablelist package defines the virtual event `<<Button3>>` as `<Button-3>` for all windowing systems and additionally as `<Control-Button-1>` for Mac OS Classic and Mac OS X Aqua. If this event occurs over a header label and both the value of the `-resizablecolumns` configuration option and that of the `-resizable` option for the column corresponding to that label are true, then the width of that column is set to zero, i.e., it is made just large enough to hold all the elements in the column, including the header (but no larger than the maximum width indicated by the `-maxwidth` column configuration option), and the virtual event `<<TablelistColumnResized>>` is generated. The same action is triggered by double-clicking the resize area of a header label.
  5. The Tablelist package defines the virtual event `<<ShiftButton3>>` as `<Shift-Button-3>` for all windowing systems and additionally as `<Shift-Control-Button-1>` for Mac OS Classic and Mac OS X Aqua. If this event occurs over a header label and both the value of the `-resizablecolumns` configuration option and that of the `-resizable` option for the column corresponding to that label are true, then the width of that column is set to its last static width (if any) and the virtual event `<<TablelistColumnResized>>` is generated. The same action is triggered by double-clicking the resize area of a header label with the `Shift` key held down.

  If the tablelist's `state` is `disabled` then none of the above actions occur: the labels are completely insensitive.

  If you want to define non-default bindings for the header labels, it is recommended to associate them with the binding tag whose name is returned by the `labeltag` subcommand and make use of the helper commands `tablelist::getTablelistColumn` and `tablelist::getTablelistPath`. For example, to replace the default binding for `<Button-3>` with a script that performs a column-dependent action, you can proceed like in the code shown below:

  >     bind [.tbl labeltag] <Button-3> {
  >         puts "right-clicked on header label no. [tablelist::getTablelistColumn %W]"
  >         break
  >     }

DEFAULT BINDINGS FOR INTERACTIVE CELL EDITING
  The `tablelist::tablelist` command extends and partially redefines the bindings of some of the components of the temporary embedded widget used for interactive cell editing, which is started by pressing mouse button 1 in an editable cell (see the `-editselectedonly` option for details) or using keyboard navigation to move from one editable cell into another. If the selection type is `cell` and the location cursor is in an editable cell, then the interactive editing of the active element can also be started by pressing `Return` or `KP_Enter`.

  The affected components of the temporary embedded widget depend on the edit window: the widget itself in case of a Tk or tile checkbutton or menubutton; the edit window's entry children in case of a mentry widget; the only entry or entry-like component of the edit window in all other cases (see also the `entrypath` subcommand). The list of binding tags of these edit window components contains two addditional tags, inserted just before their path names: the binding tag whose name is returned by the `editwintag` subcommand, followed by the tag `TablelistEdit`. The bindings described below are associated with the tag `TablelistEdit`, and can be overridden for individual tablelist widgets by making use of the binding tag given by the `editwintag` subcommand.

  1. `Control-i` inserts a tabulator character into the edit window's entry or entry-like components (if any), at the point of the insertion cursor.
  2. `Control-j` inserts a newline character into the edit window's entry or entry-like components (if any), at the point of the insertion cursor.
  3. If the edit window is a text widget then `Return` and `KP_Enter` insert a newline character at the point of the insertion cursor. Otherwise they terminate the editing and destroy the edit window.
  4. `Control-Return` and `Control-KP_Enter` terminate the editing and destroy the edit window.
  5. `Escape` aborts the editing and destroys the edit window.
  6. A click with the left mouse button anywhere in the tablelist's body, outside the cell just being edited, terminates the editing in the current cell and destroys the edit window or moves it into the cell that was just clicked into if the latter is editable.
  7. When editing a cell that is not the only editable cell of the tablelist widget, `Tab` and `Shift-Tab` terminate the editing in the current cell, move the edit window into the next/previous editable cell of the tablelist, select the contents of the edit window's first entry or entry-like component (if any), and set the insertion cursor to its end. If the new edit window is a text widget then its contents are left unselected. Notice that these bindings replace the common inter-widget navigation via `Tab` and `Shift-Tab` with inter-cell navigation. Just like in the case of the text widget, `Control-Tab` and `Control-Shift-Tab` are intended to be used for widget-to-widget keyboard navigation during interactive cell editing. Unfortunately, this won't always work because some window managers intercept the latter key sequences and use them for their own purposes (like inter-workplace navigation). For this reason, Tablelist supports the additional key sequences `Meta-Tab` and `Meta-Shift-Tab` as replacements for `Control-Tab` and `Control-Shift-Tab`, respectively.
  8. When editing a cell that is not the first/last editable cell within its row, `Alt-Left`/`Alt-Right` (`Command-Left`/`Command-Right` on Mac OS Classic and Mac OS X Aqua) terminates the editing in the current cell, moves the edit window into the previous/next editable cell of the row, selects the contents of the edit window's first entry or entry-like component (if any), and sets the insertion cursor to its end. If the new edit window is a text widget then its contents are left unselected. The key sequence `Meta-Left`/`Meta-Right` has the same effect as `Alt-Left`/`Alt-Right`. If `tk_strictMotif` is false and the edit window is not a text widget then `Meta-b` and `Meta-f` behave the same as `Alt-Left` and `Alt-Right`, respectively. If the edit window is a Tk or tile checkbutton or menubutton widget then `Left`/`Right` has the same effect as `Alt-Left`/`Alt-Right`.
  9. When editing a cell that is not the first/last editable cell within its column, `Alt-Up`/`Alt-Down` (`Command-Up`/`Command-Down` on Mac OS Classic and Mac OS X Aqua) terminates the editing in the current cell, moves the edit window one line up/down within the column, selects the contents of the edit window's first entry or entry-like component (if any), and sets the insertion cursor to its end. If the new edit window is a text widget then its contents are left unselected. The key sequence `Meta-Up`/`Meta-Down` has the same effect as `Alt-Up`/`Alt-Down`. If `tk_strictMotif` is false and the edit window is not a text widget or an Iwidgets combobox, then `Control-p` and `Control-n` behave the same as `Alt-Up` and `Alt-Down`, respectively. If the edit window is a Tk or tile entry, Tk or tile checkbutton, Tk or tile menubutton, BWidget Entry, Iwidgets entryfield/spinner/spinint, or a mentry widget of type `"FixedPoint"`, then `Up`/`Down` has the same effect as `Alt-Up`/`Alt-Down`.
  10. When editing a cell that is not the first/last editable cell within its column, `Alt-Prior`/`Alt-Next` (`Command-Prior`/`Command-Next` on Mac OS Classic and Mac OS X Aqua) terminates the editing in the current cell, moves the edit window up/down by one page within the column, selects the contents of the edit window's first entry or entry-like component (if any), and sets the insertion cursor to its end. If the new edit window is a text widget then its contents are left unselected. The key sequence `Meta-Prior`/`Meta-Next` has the same effect as `Alt-Prior`/`Alt-Next`. If the edit window is not a text widget, BWidget SpinBox, Oakley combobox, or a mentry widget of type `"Date"`, `"Time"`, `"DateTime"`, `"IPAddr"`, or `"IPv6Addr"`, then `Prior`/`Next` has the same effect as `Alt-Prior`/`Alt-Next`.
  11. When editing a cell that is not the only editable cell of the tablelist widget, `Alt-Home`/`Alt-End` (`Command-Home`/`Command-End` on Mac OS Classic and Mac OS X Aqua) terminates the editing in the current cell, moves the edit window into the first/last editable cell of the tablelist, selects the contents of the edit window's first entry or entry-like component (if any), and sets the insertion cursor to its end. If the new edit window is a text widget then its contents are left unselected. The key sequence `Meta-Home`/`Meta-End` has the same effect as `Alt-Home`/`Alt-End`. If `tk_strictMotif` is false and the edit window is not a text widget then `Meta-<` and `Meta->` behave the same as `Alt-Home` and `Alt-End`, respectively. If the edit window is not a text widget then `Control-Home`/`Control-End` has the same effect as `Alt-Home`/`Alt-End`.

  Before moving the edit window, the key sequences mentioned under 7 - 11 move the active item or element and change the (cell)selection and the (cell)selection anchor in the body of the tablelist widget. For example, if `Alt-Up`/`Alt-Down` or `Meta-Up`/`Meta-Down` (`Command-Up`/`Command-Down` on Mac OS Classic and Mac OS X Aqua) is pressed when editing a cell that is not the first/last editable cell within its column, then the active item or element (depending on the selection type) moves one line up/down. If the selection mode is `browse` or `extended` then the new active item or element is also selected and all other items or elements are deselected. In `extended` mode the new active item or element becomes the (cell)selection anchor. This is exactly the same behavior as the one exhibited by the `Up` and `Down` keys in the tablelist's body.

  If the tablelist's `state` is `disabled` then none of the above actions occur.
