buster%netscape.com 953b2efb58 nsStyleConsts.h added some HTML 4 consts for tables
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
