# 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

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.

# 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

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`.
