gt (version 0.2.2)

opt_css: Option to add custom CSS for the table

Description

The opt_css() function makes it possible to add CSS to a gt table. This CSS will be added after the compiled CSS that gt generates automatically when the object is transformed to an HTML output table. You can supply css as a vector of lines or as a single string.

Usage

opt_css(data, css, add = TRUE, allow_duplicates = FALSE)

Arguments

data

A table object that is created using the gt() function.

css

The CSS to include as part of the rendered table's <style> element.

add

If TRUE, the default, the CSS is added to any already-defined CSS (typically from previous calls of opt_table_font(), opt_css(), or, directly setting CSS the table.additional_css value in tab_options()). If this is set to FALSE, the CSS provided here will replace any previously-stored CSS.

allow_duplicates

When this is FALSE (the default), the CSS provided here won't be added (provided that add = TRUE) if it is seen in the already-defined CSS.

Value

An object of class gt_tbl.

# as string and be sure to set the table
# ID explicitly (here as "one")
