您可以尝试：

$row_count =0;
while($data = $result->fetch_assoc()) {
    $row_count++;
    $tbl .=' <tr>                                   
        <td>' .'&nbsp;' .$data['houseNumber'].'</td>
        <td>' .'&nbsp;'.$data['tenantName'].'</td>
        <td>' .'&nbsp;'.$data['status'].'</td>                      
        <td>' .'&nbsp;'.$data['rentDue'].'</td>                      
        <td>' .'&nbsp;'.$data['rentPaid'].'</td>
        <td></td>
        <td></td>
        <td></td>
        <td>'.'&nbsp;' .($data['rentPaid']).'</td>
    </tr> ';     

    if ($row_count % 3 == 0) { 
        //if is divisible for 3, put the blanck row
        $tbl .=' <tr>                                   
            <td colspan="9">&nbsp;</td>
        </tr> ';        
    } 
}
//end while
