For easier customization, the formatting of a tibble is split
into three components: header, body, and footer.
The tbl_format_footer() method is responsible for formatting the footer
of a tibble.
Override or extend this method if you need to change the appearance
of the footer.
The default implementation adds information about rows and columns
that are not shown in the body.
# NOT RUN {setup <- tbl_format_setup(palmerpenguins::penguins)
tbl_format_footer(palmerpenguins::penguins, setup)
# Shortcut for debuggingtbl_format_footer(setup)
