Title: It is totally valid (and in my opinion, semantically better) to use row-...

...based th elements (usually with a scope attribute of "row"), to differentiate between a row header and actual row data. This commit fixes the selectors for the fixedColumns attribute so that both td and th elements in the tbody to be fixed. I think a more long-term solution would be to enforce the use of row-level th elements and only set those columns to be fixed. But for now, this accounts for both. Great project. Hope this helps.
