Location helper for targeting the column spanners

The cells_column_spanners() function is used to target the cells that contain the table column spanners. This is useful 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_column_spanners(spanners)

Arguments

spanners	The names of the spanners that are to be targeted.

Value

A list object with the classes cells_column_spanners 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 `exibble` to create a gt table; add a
# spanner column label over three column
# labels and then use `tab_style()` to make
# the spanner label text bold
tab_1 <-
  exibble %>%
  dplyr::select(-fctr, -currency, -group) %>%
  gt(rowname_col = "row") %>%
  tab_spanner(
    label = "dates and times",
    columns = vars(date, time, datetime)
  ) %>%
  tab_style(
    style = cell_text(weight = "bold"),
    locations = cells_column_spanners(spanners = "dates and times")
  )
