you would need to add an if statement around each row to only show that row if there is a value in the database:
for example:
<?php if(($row_WADAnorthstar['Address1'] != "") || ($row_WADAnorthstar['Suite_Number'] != "")) { ?>
<tr class="<?php echo $WARRT_AltClass1->getClass(true); ?>">
<td bgcolor="#FFFFFF" class="WADAResultsTableCell"><?php echo $row_WADAnorthstar['Address1']; ?> <?php echo $row_WADAnorthstar['Suite_Number']; ?></td>
</tr>
<?php } ?>
