Title: include colgroups in the fixed header table

The tables I am working with use colgroups and css to style the column colors. But this gets lost in the headers once they become `fixed`.

So I clone the colgroups as before the headers.

I am not very familiar with the FixedHeader api, so this probably is not the best way to implement.
