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. The 'column_spanners' location is generated by one or more uses of the tab_spanner() function or the tab_spanner_delim() function.

cells_column_spanners(spanners = everything())

## 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.

## 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 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",
id = "dt",
columns = c(date, time, datetime)
) %>%
tab_style(
style = cell_text(weight = "bold"),
locations = cells_column_spanners(spanners = "dt")
)
