[1] [2] [3] [4] Would it not work if the cell pointed to were marked up as a th instead of marking it up as a td? If a cell is a header to the point of having the headers attribute point to it, why isn't it a header to the point of being marked up as th? (Guiding authors to mark their header cells as th is the onramp to get into a situation where the headers attribute can fade away in most cases once automatic association algorithm implementations enter the installed base.) -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
