table question

Hello

I have a table in the form of:

<table>
    <tr>
          <td></td>
          <td></td>
          <td></td>
    </tr>
    <tr>
          <td></td>
          <td></td>
    </tr>
</table>

Code (markup):

Thing is, i need to center the cells from the bottom row, cause they show like this:
__ __ __
__ __

and i can't seem to be able to do it. If i add padding or change the width of those two cells, the change goes for the top cells too. I'm lost, any ideas?

 

solved, i spawned a bottom cell and nested another table inside it, containing only two columns.
