php loops

Code:
<?php
$result = mysql_query( "SELECT * FROM reminder_events ORDER BY reminder_date DESC" );
$nr = mysql_num_rows( $result );
if(empty($nr))
{
echo("
<tr>
<td colspan='3'>No Reminders setup</td>
</tr>
");
}
while( $row = mysql_fetch_array( $result ))
{
$reminder_name = $row["reminder_name"];
$reminder_desc = $row["reminder_desc"];
$reminder_date = $row["reminder_year"]."-".$row["reminder_month"]."-".$row["reminder_date"];
$reminder_id = $row["reminder_id"];

echo("

<tr>
<td width='20%' id=reminder_body_name>$reminder_name</td>
<td width='60%' id=reminder_body>$reminder_desc</td>
<td width='10%' id=reminder_body_date>$reminder_date</td>
<td width='10%'><a href='reminder_list.php?reminder_id=$reminder_id'>delete</a></td>
</tr>
");
}
mysql_free_result( $result );
?>

The above code is working fine but I am trying to introduce a double line break after each set oif results - ie after the line:
<td width='10%'><a href='reminder_list.php?reminder_id=$reminder_id'>delete</a></td>
</tr>
If I use the <br /> tag it is just appended to the top of the page
