(Since Jeremy brought up the topic of spanning...) table.cc can handle colspan=0, so this just makes html.cc accept it as valid. from the spec: "The value zero ("0") means that the cell spans all columns from the current column to the last column of the column group (COLGROUP) in which the cell is defined." <table border=2> <tr> <td>A</td><td colspan=h>colspan=h</td></tr> <tr> <td>A</td><td colspan=-2>colspan=-2</td></tr> <tr> <td>A</td><td colspan=0>colspan=0</td></tr> <tr> <td>A</td><td colspan=1>colspan=1</td></tr> <tr> <td>A</td><td colspan=2>colspan=2</td></tr> <tr> <td>B</td><td>C</td><td>D</td><td>E</td><td>F</td></tr> </table>
