Agreed, in fact if everyone used tables for tabular data only, we could have nice browser-supplied column-reordering and row resorting, I think. Right now that kind of thing is intractable because there's no easy way to distinguish a table-for-data from a table-for-layout. I think it could be cool to have some way of putting something in your page HEAD that means: "In this page, tables are used exclusively for tabular data: you can activate your reordering features".
