It is quite difficult to see, what you expect to render from the code.
As there is no any neighbor rows and columns, colspan=”3″ is optimized to colspan=”1″. In standard scenarios, like below, colspans work correctly.

<table border=1 width=100 height=100>
<tr>
<td class="blank" colspan="3"> </td>
</tr>
<tr>
<td class="blank"> </td>
<td class="blank"> </td>
<td class="blank"> </td>
</tr>
</table>
