ขอถามเรื่องการจัดอันดับของตัวเลขหน่อยครับ !!!!!!!!!!!!!

<?
$sql ="select * from q_".$datatopic." order by no desc";
$objQuery = mysql_query($sql) or die ("Error Query [".$sql."]");
$num_rows = mysql_num_rows($objQuery);
?>

<?
while ($i < $num_rows){
	$result = mysql_fetch_array($objQuery);

	$no = $result["no"];
	$topic = $result["topic"];
	$mass = $result["mass"];
	$name = $result["name"];
	$date = $result["date"];
	$r = $result["r"];
	$a = $result["a"];

	echo "<tr><td height=10 width=10% align=center bgcolor=#CCCCCC>$no</td>";
	echo "<td height=10 width=40% align=left bgcolor=#CCCCCC><A HREF=ans.php?no=$no&g=$datatopic>$topic</td>";
	echo "<td height=10 width=15% align=left bgcolor=#CCCCCC>$name</td>";
	echo "<td height=10 width=19% align=center bgcolor=#CCCCCC>$date</td>";
	echo "<td height=10 width=8% align=center bgcolor=#CCCCCC>$r</td>";
	echo "<td height=10 width=8% align=center bgcolor=#CCCCCC>$a</td>";
	$i++;
}
?>
