Location helper for targeting row groups

The cells_row_groups() function is used to target the table's row groups when applying a footnote with tab_footnote() or adding custom style with tab_style(). The function is expressly used in each of those functions' locations argument.

cells_row_groups(groups = TRUE)

Arguments

groups	The names of the row groups that are to be targeted.

Value

A list object with the classes cells_row_groups and location_cells.

Details

When using any of the location helper functions with an appropriate function that has a locations argument, multiple locations can be targeted by enclosing several cells_*() helper functions in a list(). The following helper functions can be used to target cells (roughly in order from the top to the 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, which appear above the column labels.

• cells_column_labels(): targets the column labels.

• 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

Examples

# Use `pizzaplace` to create a gt table
# with grouped data; add a summary with the
# `summary_rows()` function and then add a
# footnote to the "peppr_salami" row group
# label with `tab_footnote()` and with
# `cells_row_groups()` in `locations`
tab_1 <-
  pizzaplace %>%
  dplyr::filter(
    name %in% c("soppressata", "peppr_salami")
  ) %>%
  dplyr::group_by(name, size) %>%
  dplyr::summarize(
    `Pizzas Sold` = dplyr::n()
  ) %>%
  gt(rowname_col = "size") %>%
  summary_rows(
    groups = TRUE,
    columns = vars("Pizzas Sold"),

    decimals = 0,
    use_seps = TRUE
  ) %>%
  tab_footnote(
    footnote = "The Pepper-Salami.",
    cells_row_groups(groups = "peppr_salami")
  )
#> `summarise()` regrouping output by 'name' (override with `.groups` argument)
