The cells_source_notes()
function is used to target all source notes in the
footer section of the table. This is useful for adding custom styles to the
source notes with tab_style()
(using the locations
argument). The
'source_notes' location is generated by the tab_source_note()
function.
This location helper function cannot be used for the locations
argument of
tab_footnote()
and doing so will result in a warning (with no change made
to the table).
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 thegroups
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 thetab_stubhead()
function.cells_column_spanners()
: targets the spanner column labels with thespanners
argument; spanner column labels appear above the column labels.cells_column_labels()
: targets the column labels with itscolumns
argument.cells_row_groups()
: targets the row group labels in any available row groups using thegroups
argument.cells_stub()
: targets row labels in the table stub using therows
argument.cells_body()
: targets data cells in the table body using intersections ofcolumns
androws
.cells_summary()
: targets summary cells in the table body using thegroups
argument and intersections ofcolumns
androws
.cells_grand_summary()
: targets cells of the table's grand summary using intersections ofcolumns
androws
cells_stub_summary()
: targets summary row labels in the table stub using thegroups
androws
arguments.cells_stub_grand_summary()
: targets grand summary row labels in the table stub using therows
argument.cells_footnotes()
: targets all footnotes in the table footer (cannot be used withtab_footnote()
).cells_source_notes()
: targets all source notes in the table footer (cannot be used withtab_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
Let's use a subset of the gtcars
dataset to create a gt table. Add a
source note (with tab_source_note()
) and style the source notes section
inside the tab_style()
call by using the cells_source_notes()
helper
function for the targeting via the locations
argument.
gtcars |>
dplyr::select(mfr, model, msrp) |>
dplyr::slice(1:5) |>
gt() |>
tab_source_note(source_note = "From edmunds.com") |>
tab_style(
style = cell_text(
color = "#A9A9A9",
size = "small"
),
locations = cells_source_notes()
)
