cell_style {reactablefmtr}

Add custom styles to cells

Description

Use 'cell_style()' to customize the appearance of certain cells in a reactable or reactablefmtr table. Assign custom styles by either row number(s) or by values within a particular column. The font color, font size, font style, and font weight can all be modified. Borders can also be placed around cells and customized by style, width, and color. By default, animation is applied to the cells that are styled, but can be turned off by setting to 'none'. Some options within 'cell_style()' will work with other reactablefmtr formatters (such as data_bars() and color_tiles()), but it is not fully supported and should be used separately, not together. 'cell_style()' needs to be placed within the style argument of reactable::colDef.

Usage

cell_style(
  data,
  rows = NULL,
  values = NULL,
  font_color = NULL,
  font_size = NULL,
  font_style = "normal",
  font_weight = "normal",
  horizontal_align = "right",
  vertical_align = "top",
  text_decoration = NULL,
  border_width = NULL,
  border_style = NULL,
  border_color = NULL,
  background_color = NULL,
  animation = "1s ease"
)

         columns = list(
           Sepal.Length = colDef(
             style = cell_style(data,
