In HTML 4, the headers/id is not a "'spesific identifaction' method by which all data cells are explicitly associated with all their corresponding header cells". Instead, just like HTML 5, HTML 4 has its own algorithm for associating headers. And in HTML 4, the headers-id method simply interacts with that algorithm. But of coursre, using @headers in - as you say - "all data cells", will naturally take presedence and nullify that algorithm 100%. > I think if headers-id method is used, then "scope" should not be > allowed for that particular data table.

If we discuss your spesific usecase, namely applying @headers in *every* data cell, then there should be no problems - it would overwrite the effect of the @scope -- I suppose. -- leif halvard silli
