nsHTMLAtoms.cpp,h added some HTML 4 strings for tables nsHTMLParts.h added constructors for new table content classes nsGenericHTMLElement.cpp,h added table frame creation, common table attribute parsing nsHTMLTable*Element.cpp these are the new table content classes nsHTMLContentSink.cpp enabled the new content and removed the old nsHTMLStyleSheet.cpp fixed the table style optimizations to work with new content nsTable*Frame.cpp these work with the new content
