you just need to add the a href code around the address:
<td class="WADADataTableCell"><a href="mailto:<?php echo($row_WADAmembertable['Contact']); ?>"><?php echo($row_WADAmembertable['Contact']); ?></a></td>
<td class="WADADataTableCell"><a href="<?php echo($row_WADAmembertable['Website']); ?>"><?php echo($row_WADAmembertable['Website']); ?></a></td>
