kableExtra 1.4.0

New Features:

• Added live preview of inline plots (#777).
• Add feature to scale_up and scale_down latex tables (#753)
• Added row grouping feature with row_group_label_position = first option (#711).
• Expanded the functionality of spec_color to allow arbitrary palettes.
• Removed dependency on rvest and glue
• In previous versions, kableExtra manipulated knitr’s global settings to auto format tables. In 1.4.0, we introduced a markdown table parser, which will parse the inputting markdown table back to a dataframe and resend it to the kbl function. In this way, all the auto formatting happens within this package. In terms of latex table specifically, we also turned on booktabs and longtable by default to mimic the default behavior of how pandoc handle markdown tables. As a result, most users won’t even feel the change. The only part that gets impacted is the table labels or references set within the kable function through the label option. For this part, first, people can set labels using knitr chunk options. Also, people can easily overcome it by either using kbl or setting format in kable.
• Added line_col to spec_pointrange()

Improvements:

• Updated kbl() parameters to match current knitr version 1.45 (#784).
• Adjusted placement of collapsed row labels to account for cmidrules within a section (#787).
• Enhanced footnote examples and fixed footnote label when notation is “none” in “pipe” output (#792).
• Enhanced text input for font_size for better customization (#576).

Bug Fixes:

• Fixed a bug in current column_spec that prevents finding the correct rows (#791).
• Resolved centering issue of three-part tables (#789).
• Corrected behavior of special characters in captions (#788).
• Fixed obscure but legal case with YAML in multi-output context (#781).
• Addressed issue with blank table in Rmarkdown inline rendering with dark-themed Rstudio (#689).
• Fixed output type detection in .onLoad and handled HTML kable object including extra stuff, like a style block.
• Fixed minor spelling errors and typos in various places (#779, #709, #710, #676).
• Resolved issue with auto_format default setting (#749).
• Some table additions didn’t work with custom rule widths (#806).

Documentation and Maintenance:

• Documented special cases and added heads-up about typo in linebreak.R (#679).
• Added Github action to run R CMD check, necessitating pdflatex and vignette compaction (#780).
• Defaulted to booktabs=TRUE, longtable=TRUE when converting a pipe table (#778).
• Declared LaTeX packages with each kbl() call and exported use_latex_packages() for user flexibility (#782).

Misc:

• Converted CSS colors like “darkgoldenrod2” to rgba() form for better compatibility (#785).
• Made various minor changes and namespace qualifications for improved functionality.
• Merged various pull requests improving codebase and resolving issues (#800, #799, #797, #798, #794, #793, #768, #632, #628, etc.).

kableExtra 1.3.1, 1.3.3, 1.3.4

• Bug fixes

kableExtra 1.3.0

Major Change

• Added a header_separate function that simplifies the workflow of adding header rows to grouped data. For example, if the original dataframe has columns in the form of “var”, “a_mean”, “a_sd”, “b_mean” and “b_sd”, this header_separate will change the column names of the 1st row to be “var”, “mean”, “sd”, “mean” and “sd” and add an additional row with group a and b there.

• @r2evans significanntly improved the previous spec_** functions to generate mini plots. He also added a more general spec_plot function to use the base R general plot function (scatter, line / polygon).

• Added a spec_pointrange function for forest-plot like figures.

Bug fixes

• Quite a lot. Somehow I forgot to document these changes this round…

kableExtra 1.2.1

Major Change

Minor Change

• Added a new_tab option to cell_spec to control whether to open up links in new tab. (#454)

• Improved the behavior of scroll_box so it will skip non-html tables. (#450)
