The cells_stub() function is used to target the table's stub cells and it is useful when applying a footnote with tab_footnote() or adding a custom style with tab_style(). The function is expressly used in each of those functions' locations argument. Here are several ways that a stub location might be available in a gt table: (1) through specification of a rowname_col in gt(), (2) by introducing a data frame with row names to gt() with rownames_to_stub = TRUE, or (3) by using summary_rows() or grand_summary_rows() with neither of the previous two conditions being true.

cells_stub(rows = everything())

Arguments

rows

The names of the rows that are to be targeted.

Value

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