Does anyone know how to make an entire bullet proof button clickable instead of just the text? Here is an example of code I have used to generate a bullet proof button but would love to know if there's a way to make the entire button clickable and have it be supported in all mail clients.

<table cellspacing="0" cellpadding="0">
  <tr>
    <td height="44" align="center" bgcolor="#3498db" style="background: color:#3498db; box-shadow:0 3px 7px #666666; -moz-box-shadow:0 3px 7px #666666; border-radius: 6px; -moz-border-radius: 6px; -webkit-border-radius: 6px;"><table width="100%" cellspacing="0" cellpadding="0">
      <tr>
        <td width="35">&nbsp;</td>
        <td><strong><a style="color: #ffffff; text-decoration: none" href="#"><font color="#ffffff" face="Arial, Helvetica, sans-serif" size="2" style="font-size: 15px; text-decoration: none;" class="mobile_text1">Read More</font></a></strong></td>
        <td width="35">&nbsp;</td>
      </tr>
    </table></td>
  </tr>
</table>
