The cell_fill() helper function is to be used with the tab_style() function, which itself allows for the setting of custom styles to one or more cells. Specifically, the call to cell_fill() should be bound to the styles argument of tab_style().


cell_fill(color = "#D3D3D3", alpha = NULL)



Cell fill color

scalar<character> --- default: "#D3D3D3"

If nothing is provided for color then "#D3D3D3" (light gray) will be used as a default.


Transparency value

scalar<numeric|integer>(0>=val>=1) --- default: NULL (optional)

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.


A list object of class cell_styles.


Let's use the exibble dataset to create a simple, two-column gt table (keeping only the num and currency columns). Styles are added with tab_style() in two separate calls (targeting different body cells with the cells_body() helper function). With the cell_fill() helper funciton we define cells with a "lightblue" background in one instance, and "gray85" in the other.

exibble |>
  dplyr::select(num, currency) |>
  gt() |>
  fmt_number(decimals = 1) |>
    style = cell_fill(color = "lightblue"),
    locations = cells_body(
      columns = num,
      rows = num >= 5000
  ) |>
    style = cell_fill(color = "gray85"),
    locations = cells_body(
      columns = currency,
      rows = currency < 100

This image of a table was generated from the first code example in the `cell_fill()` help file.
