How to set padding in header cells of htmlTable package?

I am using htmlTable package in my rmarkdown files. For setting cell padding I use this piece of code: 

htmlTable(..., css.cell = "padding-left: .5em; padding-right: .2em;")

How can I do something similar on the header cells?

The key is to add the + 1 rows when specifying the css.cell matrix argument. The default is to only affect the data-cells. Here's an example:

simple_output <- matrix(1:4, ncol = 2)
htmlTable(simple_output,
          header = LETTERS[1:2],
          css.cell = rbind(rep("background: lightgrey; font-size: 2em; padding-left: .5em; padding-right: .2em;", 
                               times = ncol(simple_output)),
                           matrix("", 
                                  ncol = ncol(simple_output), 
                                  nrow = nrow(simple_output))))

New to R I really appreciate this fantastic htmlTable package thank you Max Gordon.

The +1 did not work for me for some reasons (I have some tspanner?).

You can still do the formatting by adding the html code to your rownames, e.g. I want to format in italic the NA's rows header in my table:

rl[which(rl == "NA's")] <- rep("<i>NA's", length(which(rl == "NA's")))

Where rl is the vector of my rows headers

Hope it helps
