filling the table its easy. but how do i tell to add a <tr> to every 3 records??

<?php if($totalRows_rsSdk>0){
do{
?>
<td align="center" valign="middle"><input type="checkbox" class="css-checkbox" name="sdkcheck" id="sdkcheck<?php echo $row_rsSdk['id']; ?>"/><label for="sdkcheck<?php echo $row_rsSdk['id']; ?>" class="css-label2 radGroup3"><?php echo $row_rsSdk['nome']; ?></label></td>

Try this code:
<table width="30%" border="0">
<tbody>
<tr>
<?php if($totalRows_rsSdk>0){
$counter = 0;
do{
?>
<td align="center" valign="middle"><input type="checkbox" class="css-checkbox" name="sdkcheck" id="sdkcheck<?php echo $row_rsSdk['id']; ?>"/><label for="sdkcheck<?php echo $row_rsSdk['id']; ?>" class="css-label2 radGroup3"><?php echo $row_rsSdk['nome']; ?></label></td>
<td align="center" valign="middle"><img src="Images/sdk-icons/<?php echo $row_rsSdk['icon']; ?>" height="70"></td>
<?php
$blockSize = 3;
$counter++;
if ($counter >= $blockSize) {
$counter = 0;
?>
</tr>
<tr>
<?php
}
} while ($row_rsSdk = mysql_fetch_assoc($rsSdk));} ?>
<?php echo str_repeat('<td></td>',($blockSize-$counter)); ?>
</tr>
</tbody>
</table>
