# flextable 0.9.10

## new features

- It is now possible to not repeat headers'rows along Word pages
by using `set_table_properties(opts_word = list(repeat_headers = FALSE))`.

## Issues

- fix `format_fun.default` so that it works with logical columns.

## Change

- `print.flextable(preview = "log")` use `str()` to show first values of data
instead of `print()` so that when there are ggplot2 v4 objects in the table, the 
print is not failing.

# flextable 0.9.9

## new features

- `proc_freq` gains new argument `count_format_fun` to let control the function 
that format the count values.

## Issues

- fix compatibility issue with rmarkdown::word_document and quarto introduced with
version `0.9.8`.

## Changes

- Defunct previously deprecated functions `as_raster()`, `lollipop()` 
  and `set_formatter_type()`.
- Definitively forbid usage of empty symbol `''` with footnotes. Users should 
  use `add_footer_lines()` instead.

# flextable 0.9.8

## Issues

- `tab_settings()` is now using j argument as expected (#635)
- doc inconsistency for `set_table_properties()` with layout that defaults to 
"fixed".
- add_header_row produced an error after using `delete_column()` (#676)
- `fmt_signif_after_zeros()` fixed issue with 0 rounding
- `proc_freq` supports now non syntactically names

# flextable 0.9.7

## new features

- Added support for labelled datasets.

## Changes

- The `fix_border_issues` function is now useless for users, as it is now 
called automatically before printing.

## Issues

- fix caption issue that came with no version of bookdown (issue #645),
'bookdown' management of caption has been simplified.
- fix vertical overlapping lines with grid output (issue #644)
- fix broken internal links in PDF file, probably due to a change in knitr or 
rmarkdown (issue #632)
- fix right outer border issue in grid format (issue #650)
- fix `flextable_to_rmd()` issue with images in pdf (issue #651)
- fix `flextable_to_rmd()` issue with local chunk `eval` option (issue #631)
- `proc_freq` can now display only the table percentages without the count 
using `include.table_count = FALSE`.
- bring back support for 'pagedown' with `pagedown >= 0.20.2`
- flextable now applies defined text-format to empty cells for Word and
Powerpoint outputs.

# flextable 0.9.6

## Changes

- `headers_flextable_at_bkm()` and `footers_flextable_at_bkm()` are defunct.
- `flextable_to_rmd()` is now using `knit_child()` for safer usage from `for`
  loops or `if` statements.
- Add explanation about caption limitations in the manual of functions
  `save_as_image()` and `ph_with.flextable()`.
- Deprecate `as_raster()` since `gen_grob()` is easier to use and render
  nicer.
- BREAKING CHANGE: in `align()`, the default argument value for `align` is now
  `"left"`, rather than `c("left", "center", "right", "justify")`. This
  returns the default value to how it was in older versions of {flextable}.
    - in `align()`, use of the old default `align` argument could cause an
      error if the number of columns being adjusted was not a multiple of 4.
    - The documentation specified that `align` had to be a single value, when
      it could actually accept multiple values. This is why a default value of
      `c("left", "center", "right", "justify")`, was problematic. This
      documentation has now been updated and new examples included in the
      documentation.
    - The default `align` argument will now apply left alignment to all
      columns in the body.
    - If the user specifies an alignment that is invalid, a error will be
      displayed.
    - The `path` argument now has a signature of `part = c("body", "header",
      "footer", "all")`, but because only a single value can be selected, it
      will pick `"body"` by default, as before.
- Deprecate `lollipop()` since it produces (ugly) results that can be replaced
by nice results with `gg_chunk()` or `grid_chunk()`.

## Issues

- fix issue with `as_image()` when the table contains no text.
- fix font instruction issue with PDF and quarto
- fix issue with Quarto detection and R > 4.4
- fix `align()` issue with recycling and update documentation
that was wrong about argument `align` that is vectorized over 
columns.

# flextable 0.9.5

## new features

- new functions `tab_settings()` to set tabulation marks configuration
for Word and RTF. It works with `officer::fp_tabs()`.
- new function `fmt_signif_after_zero()` to round significant figures after zeros.

## Issues

- `summarizor()` don't stop anymore if table only contain discrete columns.
- `as_flextable.data.frame()` supports 'data.table'
- `footnote()` handle undefined `ref_symbols` argument
- `delete_rows()` does not delete rows if the row selection is empty
- improve `gen_grob()` alignments when wrapping text
- fix horizontal border issue with `gen_grob()` when cells are vertically merged
- Word captions set with `set_caption()` can have no bookmark and have
autonumber used together.

## Changes

- default `tabcolsep` is now set to 2.
- Deprecate `set_formatter_type()`.
- renovate `fmt_2stats()` so that it uses global flextable settings, 
i.e. digits, etc.
- refactoring of data structure for content
- footer along pages in PDF are now deactivated by default. It can be 
activated with command `set_table_properties(opts_pdf = list(footer_repeat = TRUE))`.
- more argument checkings in `as_chunk()`

# flextable 0.9.4

## Issues

- `ph_with.flextable()` formats widths and heights correctly.
- move image shown in add_footer to footnote where it should be.
- update the documentation and automatically change alignment
'justify' to 'left' for latex output.
- borders'width for grid output are fixed

## new features

- new functions `delete_columns()` and `delete_rows()` 
to let users delete rows or columns.
- `save_as_image()` now supports svg export with 'svglite'.

# flextable 0.9.3

## new features

- The `summarizor()` function has been enhanced to offer three new options: 
  - an empty `by` argument meaning 'no grouping,' 
  - the ability for users to select numeric statistics to display ("mean_sd," "median_iqr," "range"), 
  - and the option to specify whether or not to show all NA counts.

## Changes

- `as_flextable.data.frame()` always shows the number of rows even if less than 10 
(because I need it!).

## Issues

- Make sure 'gfm' format is rendered as an image.
- As adviced by Ben Bolker, functions `as_flextable.lm()`, `as_flextable.gam()`,
`as_flextable.glm()`, `as_flextable.merMod()` and `as_flextable.htest()`
now respect the global value of `getOption("show.signif.stars")`.
- new argument `add.random` in `as_flextable.merMod()` to let add or not
random effects in the final table.
- drop superfluous semicolons when include.row_percent = FALSE
- Super and subscripts are now correctly
rendered in PDF (thanks to Philippe Grosjean).
- argument `max_iter` of function `fit_to_width` is not
ignored anymore.

## Internals

- rename technical column `part` to `.part` so that
column named `part` can be used.

# flextable 0.9.2

## Issues

- rmarkdown expect list of dependencies to be unnamed.
This property is used in HTML or LaTeX deps resolution to know 
when to be recursive 
- `dim_pretty()` returns correct numbers when not 'inches'
- `as_flextable.table()` now propagates `...` as expected
- pdf: when table was on two pages, there were duplicated caption entries,
this is fixed thanks to Christophe Dervieux and Nick Bart. Repeating 
the caption along pages can be desactivated with command 
`set_table_properties(opts_pdf = list(caption_repeat = FALSE))`.
- `as_flextable()` now works on tabular objects and `R < 4.1`.
- `to_html(type = "img")` now use the correct width and height

## Changes

- bookdown has now bookmarks associated with captions and flextable benefits
from this feature.
- In 'Quarto' captions are ignored, which make Quarto captions valid with HTML
and PDF outputs; the responsibility for managing captions lies with the
Quarto framework itself. It does not work with Quarto for Word and should be
possible with Quarto `1.4`.
- `as_flextable.tabular()` now generate tabulated content only if the sub group
contains more than a single row. When possible, row titles are tabulated.

## Deprecated functions

- The functions `footers_flextable_at_bkm` and `headers_flextable_at_bkm` are deprecated.
Instead, we recommend using the `prop_section()` and `block_list()` functions from the `officer` package as alternative solutions. These functions provide more reliable and flexible options for managing footers and headers. 

# flextable 0.9.1

## breaking change

- parameter `keepnext` and `ft.keepnext` are defunct, they are replaced
by function `paginate()` that enable nice pagination of tables across pages 
or `keep_with_next()` to get total control over rows pagination.

## new features

- add RTF support for captions.
- `set_flextable_defaults()` gains parameter `pct_digits` 
(number of digits for percentages) that will be used in relevant 
functions (only `proc_freq()` for now).
- new method `as_flextable.table()`.
- new functions `fmt_dbl()`, `fmt_int()` and `fmt_pct()`.
- Support for Word and RTF pagination with function `paginate()`

## internals

- refactor proc_freq and support 1d frequency table

## issues

- colname `type` is now possible when using `tabulator()`.
- value for html dependancies parameter is a list of html-dep as expected.
This solves issue for blogdown and pkgdown introduced in the previous version.
- fix `save_as_html()` ugly default title.
- fix alignment issues when rows are horizontally merged in PDF

# flextable 0.9.0

## new features

- add RTF support for captions.
- enable new labels with `set_header_labels()` from a simple
un-named vector.
- function `set_formatter()` now accepts single function to 
be applied to all columns.
- HTML output now can capture google fonts if installed with 
`gdtools::register_gfont()`.
- refactor `save_as_html()`: use rmarkdown and add google fonts
if possible (See `gdtools::register_gfont()`).

## issues

- fix `as_flextable.tabular(spread_first_col=TRUE)`

# flextable 0.8.6

In short: 

- RTF support, 
- revealjs support,
- preserve all aspects within Quarto html format
- use grid graphics for saving as png (no need for "webshot" or "webshot2" packages)
- support for `tables::tabular()`: "Computes a table of summary statistics, cross-classified by various variables"

## new features

- add RTF support with `officer::rtf_add()`.
- new convert `tables::tabular()` to flextable with new 
function `as_flextable.tabular()`.
- add `to_html.flextable()` to make easy embedding of 
flextable results in HTML (with 'ggiraph' for example).
- add global setting `border.width` (see `?set_flextable_defaults()`) 
and set its default value to .75, this setting is 
used in theme functions. The old default value was hard coded 
to 1 and can be defined during the whole R session with
`set_flextable_defaults(border.width = 1)`.

## internals

- drop 'base64enc' dependency and use 'officer' functions
as replacement. 
- Use `officer_url_encode()` to encode URL in office files.
- refactor `knit_print.flextable()` and related functions. 
- drop webshot dependency to produce images, now using package
'ragg'.
- refactor captions: knitr context now updates the caption 
instead of managing caption value and defined knitr 
options.
- use shadow in all HTML output generated via knitr 
(i.e. 'Quarto' and 'R Markdown').

## issues

- support revealjs (and probably all RMD formats that generate HTML)
- fix cell's vertical alignments in latex
- fix detection of non transparent background table in latex so that
the correct lines instructions (hhlines or clines) are being used.
- fix `headers_flextable_at_bkm()` and `footers_flextable_at_bkm()`

# flextable 0.8.5

## changes

- use pkgdown features instead of images shots 
in the manual examples. The website now shows
flextable results.

## issues

- fix issue with flextable_to_rmd and pdf introduced in `0.8.4`.
- fix caption issue with Word and `body_add_flextable()`.

# flextable 0.8.4

- new argument `expand_single` in `as_flextable.tabulator()`. If `FALSE`,
groups with only one row will not be expanded with a title row.
- argument `labels` of `labelizor()` now support functions in 
addition to named vectors.
- `as.character()` now returns the HTML string of the table
- new method `as_flextable` for data.frame using `df_printer()` function
implementation.

- Word caption: autonumber works without bookmark

# flextable 0.8.3

## new features

- new argument `expand_single` in `as_grouped_data()`. If FALSE, groups with only one
row will not be expanded with a title row.
- new functions `fmt_avg_dev()`, `fmt_header_n()`, `fmt_n_percent()` and renaming of `fmt_2stats()` 
to `fmt_summarizor()` to help working with `tabulator()`. `tabulator()` has also new
internal values that allow N=xxx notes and automatic labels.
- function `set_table_properties()` is now the recommanded way to set
arguments related to format options and alignment in a document. It is
supposed to replace "knitr" chunk options `ft.align`, `ft.split`,
`ft.keepnext`, `ft.tabcolsep`, `ft.arraystretch`, `ft.latex.float`,
`ft.shadow`, `fonts_ignore` although they are all still
supported.
This allows less interaction with the 'R Markdown' or 'Quarto'
eco-system and let to define it globally with `set_flextable_defaults()`.
- HTML scrolling can be activated by calling `set_table_properties()` and 
providing a *scroll* value for argument `opts_html`: 
`opts_html = list(scroll = list(height = "500px",freeze_first_column = TRUE))`.
- new function `grid_chunk()` to let users add grid graphics
- functions `add_header_row()`, `add_footer_row()`, `add_body_row()`,
`add_header_lines()` and `add_footer_lines()` 
now supports formatted paragraph made with `as_paragraph()`.
- captions: support for simple text in addition to `as_paragraph()`
- `summarizor()` can now be transformed directly as a flextable 
with method `as_flextable()`.

## Issues

- fix issue with keepnext and `body_add_flextable()`
- fix issue of misordered chunks with `prepend_chunks()`
- argument 'unit' is dropped in `line_spacing()` as it is expected to be a ratio

## Changes

- `ft.keepnext` now default to FALSE as lot of users had issues
with this option.
- function `xtable_to_flextable()` is removed (use `as_flextable()`)

- add support for paragraph settings (made with `fp_par()`) in captions with `set_caption()`.
- captions are now made with `as_paragraph()`
- caption alignments and keep_with_next is now computed instead of being provided by user
- alternative text for Word tables with word_title and word_description 
by calling `set_table_properties()` or setting values to knitr chunk options `tab.alt.title` and `tab.alt.description`.
- Word and HTML captions paragraphs settings can be defined by using `set_caption()`. 
The alignment of the paragraph can be different from the alignment of the table 
with the argument `align_with_table=FALSE`.
- new theme 'APA', `theme_apa` (@rempsyc #426)
- method `as_flextable.tabulator()` gains an argument `spread_first_col` to enable 
spreading of the first column of the table as a line separator.

labels to display in the first column names, i.e. the *row* column names.
- new function `shift_table()` to produce Shift Tables used used in 
clinical trial analysis ready to be used by `tabulator()`.
- `as_image()` don't need anymore parameters `width` and 
`height` if package 'magick' is available.

## Changes

- `plot.flextable` now default to *grid Graphics*. It produce a plot object 
that can be used with packages 'ggplot2', 'patchwork' and 'cowplot'. The raster
