<!-- The inner table is rendered but not the outer one. Basically if any table contains another table, it is rendered as plain text --> <table> <tr><td> First column, and an inner table: <table> <tr><td>One</td><td>Two</td></tr> <tr><td>One</td><td>Two</td></tr> </table> </td> <td>Second column</td> </tr> </table>
