The headers attribute can reference a th, so if the tds are changed to this in the example, the relationship would be complete. But that isn't allowed in the editor's draft, as nested headers aren't allowed. It isn't allowed in the spec for a cell to be a th that is in scope of another th. That seems to make sense because scope doesn't have start and end parameters. Nested headers creates a new problem of what is the automatic scope association of a th in the middle of a table: Does automatic scope apply to the row (to the left?, to the right?, both directions?), does it apply to the column (above? below? both directions?), does it apply to the row and column and various combinations? Would it require a scope, and how does that change depending on reading direction? It's all undefined, and unnecessary, as the headers attribute referencing a td works perfectly well. Like I mentioned before, we have had approximately a thousand headers messages to date on list: http://w3.markmail.org/search/?q=headers+list%3Aorg.w3.public-html+date%3A20070501-20080912 @headers has been an issue since May 1, 2007 with 40 some threads. http://esw.w3.org/topic/HTML/IssueTableHeaders#head-bac4baeb0cd0ea09b7f76ff9c409740257566408 I don't know what there is left to say. That is left to discuss? How does the working group make a decision on this? The Charter states: "...if a decision is necessary for timely progress, but after due consideration of different opinions, consensus is not achieved, the Chair should put a question (allowing for remote, asynchronous participation using, for example, email and/or web-based survey techniques) and record a decision and any objections, and consider the matter resolved." http://www.w3.org/2007/03/HTML-WG-charter.html#decisions Best Regards, Laura -- Laura L.
