Add color highlighting to a specific column(s)

The gt_highlight_cols function takes an existing gt_tbl object and adds highlighting color to the cell background of a specific column(s).

Usage

gt_highlight_cols(
  gt_object,
  columns,
  fill = "#80bcd8",
  alpha = 1,
  font_weight = "normal",
  font_color = "#000000"
)

gt_object: An existing gt table object of class gt_tbl
columns: Specific columns to apply color to, accepts either tidyeval colum names or columns by position.
fill: A character string indicating the fill color. If nothing is provided, then "#80bcd8" (light blue) will be used as a default.
alpha: An optional alpha transparency value for the color as single value in the range of 0 (fully transparent) to 1 (fully opaque). If not provided the fill color will either be fully opaque or use alpha information from the color value if it is supplied in the #RRGGBBAA format.
font_weight: A string or number indicating the weight of the font. Can be a text-based keyword such as "normal", "bold", "lighter", "bolder", or, a numeric value between 1 and 1000, inclusive. Note that only variable fonts may support the numeric mapping of weight.
font_color: A character string indicating the text color. If nothing is provided, then "#000000" (black) will be used as a default.
