My Issue/Question:
See the below screenshot. I have a table with mixed normal and angled headers. First two normal headers, then a series of angled headers. I can sort the table on the normal header and the first angled header, but not the rest. Any click on those is just ignored. (sort specs does not become dirty). This is both when clicking on the angled header or the line below it (only the normal header row works for the first angled header column, but i understand that is expected).
