Centering table

Hi folks,

I have an issue trying to center this table.

http://nutricionlaspalmas.com/liposuccion-sin-cirugia-2/

I dug up the forum and didn’t find a solution.

Here is the code of the table:

<table class="aligncenter" border="1" cellspacing="0" cellpadding="0">
<tbody>
<tr>
<td colspan="3" valign="top" width="489">
<p style="text-align: center;" align="center">LIPOSUCCIÓN SIN CIRUGIA</p>
</td>
</tr>
<tr>
<td colspan="2" valign="center" width="288">
<p align="center">SESIONES</p>
</td>
<td valign="top" width="201">
<p align="center">ASESORAMIENTO NUTRICIONAL (quincenal)</p>
</td>
</tr>
<tr>
<td valign="top" width="144">
<p align="center">1/SESION</p>
</td>
<td valign="top" width="144">
<p align="center">30€</p>
</td>
<td valign="top" width="201">
<p align="center">25€</p>
</td>
</tr>
<tr>
<td valign="top" width="144">
<p align="center">10/SESIONES</p>
</td>
<td valign="top" width="144">
<p align="center">285€</p>
</td>
<td valign="top" width="201">
<p align="center">20€</p>
</td>
</tr>
<tr>
<td valign="top" width="144">
<p align="center">15/SESIONES</p>
</td>
<td valign="top" width="144">
<p align="center">405€</p>
</td>
<td valign="top" width="201">
<p align="center">20€</p>
</td>
</tr>
<tr>
<td valign="top" width="144">
<p align="center">20/SESIONES</p>
</td>
<td valign="top" width="144">
<p align="center">510€</p>
</td>
<td valign="top" width="201">
<p align="center">GRATUITAS</p>
</td>
</tr>
</tbody>
</table>

It only works with left and right, with aligncenter it does that wierd thing adding a frame to the table. Any suggestions?

Thanks in advance!
