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 recommended 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())
