Michael Johnson thinks its difficult to implement VALIGN in table cells: > It would be easy *IF* you assumed that the maximum of any HEIGHT attributes > in a row was in fact the maximum height for the row, which may not be a > valid assumption.

There are no HEIGHT attributes defined in the draft HTML 3.0 dtd for rows or cells for that matter. The browser makes a prepass to allocate suitable columns widths (unless these are predefined by a colspec). It then formats each cell, one at a time. The vertical offset for each cell is worked out trivially at display time, as by then the row height is known (you don't know it until you have formatted all cells in a row). This is another example of how in computing you should put until tomorrow what you can't do today! -- Dave Raggett <dsr@w3.org> tel: +44 272 228046 fax: +44 272 228003 Hewlett Packard Laboratories, Filton Road, Bristol BS12 6QZ, United Kingdom
