The way sighted users work with the obvious case is that for a given cell <td> they look up the column until they reach a <th> and to the left (assuming ltr text) until they find a <th> and use those as the column and row headings. To me, it seems like a no-brainer that for practical usefulness, a screen reader should walk tables like this in the absence of explicit association. Implementing table walking like this is a much better way to improve table accessibility than requiring authors to be explicit about the associations in the most common and obvious case. Do any screen readers do this? If not, why not? If not, shouldn't the first priority for accessibility experts who want to make HTML tables more accessible be lobbying screen reader vendors to bother to walk the table model like this? (I tried to test this in VoiceOver, but I couldn't find documentation about keyboard commands querying a table cell for its headers.) -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
