Location helper for targeting the source notes

The cells_source_notes() function is used to target all source notes in the footer section of the table. This is useful for adding custom styles to the source notes with tab_style() (using the locations argument). The 'source_notes' location is generated by the tab_source_note() 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).

Usage

cells_source_notes()

Value

A list object with the classes cells_source_notes 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

Let's use a subset of the gtcars dataset to create a gt table. Add a source note (with tab_source_note()) and style the source notes section inside the tab_style() call by using the cells_source_notes() helper function for the targeting via the locations argument.

gtcars |>
  dplyr::select(mfr, model, msrp) |>
  dplyr::slice(1:5) |>
  gt() |>
  tab_source_note(source_note = "From edmunds.com") |>
  tab_style(
    style = cell_text(
      color = "#A9A9A9",
      size = "small"
    ),
    locations = cells_source_notes()
  )
