cells_column_labels | R Documentation |
The cells_column_labels()
function is used to target the table's column
labels 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_labels' location is present by
default in every gt table.

Columns to target
The columns to which targeting operations are constrained. Can either
be a series of column names provided in |
A list object with the classes cells_column_labels
and
location_cells
.
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())
).
columns
argumentThe columns
argument allows us to target a subset of columns contained in
the table. We can declare column names in c()
(with bare column names or
names in quotes) or we can use tidyselect-style expressions. This can be
as basic as supplying a select helper like starts_with()
, or, providing a
more complex incantation like
where(~ is.numeric(.x) && max(.x, na.rm = TRUE) > 1E6)
which targets numeric columns that have a maximum value greater than
1,000,000 (excluding any NA
s from consideration).
Let's use a small portion of the sza
dataset to create a gt table.
Add footnotes to the column labels with tab_footnote()
and
cells_column_labels()
in locations
.
sza |> dplyr::filter( latitude == 20 & month == "jan" & !is.na(sza) ) |> dplyr::select(-latitude, -month) |> gt() |> tab_footnote( footnote = "True solar time.", locations = cells_column_labels( columns = tst ) ) |> tab_footnote( footnote = "Solar zenith angle.", locations = cells_column_labels( columns = sza ) )
