Location helper for targeting the footnotes

The cells_footnotes() function 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 the tab_footnote() function. 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).

cells_footnotes()

Value

A list object with the classes cells_footnotes and location_cells.

Overview of Location Helper Functions

Location helper functions can be used to target cells with virtually any function that has a locations argument. Here is a listing of all of the location helper functions, with locations corresponding roughly from top to bottom of a table:

• cells_title(): targets the table title or the table subtitle depending on the value given to the groups argument ("title" or "subtitle").

• cells_stubhead(): targets the stubhead location, a cell of which is only available when there is a stub; a label in that location can be created by using the tab_stubhead() function.

• cells_column_spanners(): targets the spanner column labels with the spanners argument; spanner column labels appear above the column labels.

• cells_column_labels(): targets the column labels with its columns argument.

• cells_row_groups(): targets the row group labels in any available row groups using the groups argument.

• cells_stub(): targets row labels in the table stub using the rows argument.

• cells_body(): targets data cells in the table body using intersections of columns and rows.

• cells_summary(): targets summary cells in the table body using the groups argument and intersections of columns and rows.

• cells_grand_summary(): targets cells of the table's grand summary using intersections of columns and rows

• cells_stub_summary(): targets summary row labels in the table stub using the groups and rows arguments.

• cells_stub_grand_summary(): targets grand summary row labels in the table stub using the rows argument.

• cells_footnotes(): targets all footnotes in the table footer (cannot be used with tab_footnote()).

• cells_source_notes(): targets all source notes in the table footer (cannot be used with tab_footnote()).

When using any of the location helper functions with an appropriate function that has a locations argument (e.g., tab_style()), multiple locations can be targeted by enclosing several cells_*() helper functions in a list() (e.g., list(cells_body(), cells_grand_summary())).

# Use `sza` to create a gt table; color
# the `sza` column using the `data_color()`
# function, add a footnote and also style
# the footnotes section
tab_1 <-

  dplyr::filter(
    latitude == 20 &
      month == "jan" &
      !is.na(sza)
  ) %>%
  dplyr::select(-latitude, -month) %>%
  gt() %>%
  data_color(
    columns = sza,
    colors = scales::col_numeric(
      palette = c("white", "yellow", "navyblue"),

    )
  ) %>%

  tab_style(
    style = list(
      cell_text(size = "smaller"),
      cell_fill(color = "gray90")
      ),
    locations = cells_footnotes()
