<table> contains an incoherent number of columns on one of its rows. Check the structure of the table to find the invalid row.
For example, in the following table, the first
<tr> row defines that it’s 2 columns wide, but the second
<tr> row tries to use 5 columns by means of a
<table> <!-- This first row sets the table as 2 columns wide --> <tr> <td>First</td> <td>Second</td> </tr> <!-- This second row tries to use 5 columns --> <tr> <td colspan="5">Wrong</td> </tr> </table>
