The TableColumnBase class was added in 8.0, but contains quite a few methods marked as @since 2.2.

I suppose they existed since 2.2 in the subclass and were moved to newly created superclass. So the tags probably look correct in the subclass' doc, but looking to this class, they claim the methods had been added to the class before it was created, which is pretty confusing. We need to sort out if this is ok or if the tags should be deleted. I'm not sure.
