Location helper for targeting the stub cells in a grand summary

The cells_stub_grand_summary() function is used to target the stub cells of a grand summary and it is useful when applying a footnote with tab_footnote() or adding custom styles with tab_style(). The function is expressly used in each of those functions' locations argument. The 'stub_grand_summary' location is generated by the grand_summary_rows() function.

Usage

cells_stub_grand_summary(rows = everything())

Arguments

rows: The names of the rows that are to be targeted.

Value

A list object with the classes cells_stub_grand_summary 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())).

Examples

Use countrypops to create a gt table. Add some styling to a grand summary stub cell with with the tab_style() and cells_stub_grand_summary() functions.

countrypops %>%
  dplyr::filter(country_name == "Spain", year < 1970) %>%
  dplyr::select(-contains("country")) %>%
  gt(rowname_col = "year") %>%
  fmt_number(
    columns = population,
    decimals = 0
  ) %>%
  grand_summary_rows(
    columns = population,
    fns = list(change = ~max(.) - min(.)),
    formatter = fmt_number,
    decimals = 0
  ) %>%
  tab_style(
    style = cell_text(weight = "bold", transform = "uppercase"),
    locations = cells_stub_grand_summary(rows = "change")
  )
