Tables with multiple rows of header rows are extremely useful
to demonstrate grouped data. This function takes the output of a kable()
function and adds an header row on top of it.
add_header_above(kable_input, header = NULL, bold = FALSE, italic = FALSE,
monospace = FALSE, escape = TRUE)Output of knitr::kable() with format specified
A (named) character vector with colspan as values. For
example, c(" " = 1, "title" = 2) can be used to create a new header row
for a 3-column table with "title" spanning across column 2 and 3. For
convenience, when colspan equals to 1, users can drop the = 1 part.
As a result, c(" ", "title" = 2) is the same as c(" " = 1, "title" = 2).
A T/F value to control whether the text should be bolded.
A T/F value to control whether the text should to be emphasized.
A T/F value to control whether the text of the selected column need to be monospaced (verbatim)
A T/F value showing whether special characters should be escaped.
# NOT RUN {
x <- knitr::kable(head(mtcars), "html")
# Add a row of header with 3 columns on the top of the table. The column
# span for the 2nd and 3rd one are 5 & 6.
add_header_above(x, c(" ", "Group 1" = 5, "Group 2" = 6))
