I've got a HTML table with several cells inside, the border=0 property is set yet the border does not go away, what am I doing wrong?
<table width="500" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC">
  <tr>
    <td>
      <table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF">    
        <tr>
          <td>
            <br><br>
          </td>
        </tr>
      </table>
    </td>
  </tr>
</table>
