Location helper for targeting the footnotes

cells_footnotes() is used to target all footnotes in the footer section of the table. This is useful for adding custom styles to the footnotes with tab_style() (using the locations argument). The 'footnotes' location is generated by one or more uses of tab_footnote(). This location helper function cannot be used for the locations argument of tab_footnote() and doing so will result in a warning (with no change made to the table).

Usage

cells_footnotes()

Value

A list object with the classes cells_footnotes and location_cells.

Examples

Using a subset of the sza dataset, let's create a gt table. We'd like to color the sza column so that's done with the data_color() function. We can add a footnote with tab_footnote() and we can also style the footnotes section. The styling is done with tab_style() and locations = cells_footnotes().

sza |>
  dplyr::filter(
    latitude == 20 &
      month == "jan" &
      !is.na(sza)
  ) |>
  dplyr::select(-latitude, -month) |>
  gt() |>
  data_color(
    columns = sza,
    palette = c("white", "yellow", "navyblue"),
    domain = c(0, 90)
  ) |>
  tab_footnote(
    footnote = "Color indicates height of sun.",
    locations = cells_column_labels(columns = sza)
  ) |>
  tab_options(table.width = px(320)) |>
  tab_style(
    style = list(
      cell_text(size = "smaller"),
      cell_fill(color = "gray90")
      ),
    locations = cells_footnotes()
  )
