If your variable names contain
multiple delimited labels, they will be separated
and placed in their own rows.
Usage
separate_header(
x,
opts = c("span-top", "center-hspan", "bottom-vspan", "default-theme"),
split = "[_\\.]",
fixed = FALSE
)Arguments
- x
a flextable object
- opts
optional treatments to apply to the resulting header part as a character vector with multiple supported values.
The supported values are:
"span-top": span empty cells with the first non empty cell, this operation is made column by column.
"center-hspan": center the cells that are horizontally spanned.
"bottom-vspan": bottom align the cells treated when "span-top" is applied.
"default-theme": apply to the new header part the theme set in
set_flextable_defaults(theme_fun = ...).
- split
a regular expression (unless
fixed = TRUE) to use for splitting.- fixed
logical. If TRUE match
splitexactly, otherwise use regular expressions.
