Location helper for targeting data cells in the table body

The cells_body() function is used to target the data cells in the table body. The function can be used to apply a footnote with tab_footnote(), to add custom styling with tab_style(), or the transform the targeted cells with text_transform(). The function is expressly used in each of those functions' locations argument. The 'body' location is present by default in every gt table.

Usage

cells_body(columns = everything(), rows = everything())

Arguments

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

Value

A list object with the classes cells_body 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 gtcars to create a gt table. Add a footnote that targets a single data cell with tab_footnote(), using cells_body() in locations (rows = hp == max(hp) will target a single row in the hp column).

gtcars %>%
  dplyr::filter(ctry_origin == "United Kingdom") %>%
  dplyr::select(mfr, model, year, hp) %>%
  gt() %>%
  tab_footnote(
    footnote = "Highest horsepower.",
    locations = cells_body(
      columns = hp,
      rows = hp == max(hp)
    )
  ) %>%
  opt_footnote_marks(marks = c("*", "+"))
