Alternative tabelfarver i PHP

Hej,

Er der nogen der kan hjælpe med at rette denne PHP-kode således at hveranden række er hvid og den anden halvdel er grå?

Koden:
<table width="100%" border="1" cellpadding="5">
<tr>
<th>Player Name</th>
<th>Total Average <br>for All Matches</th>
</tr>
<?
$strSQL = "SELECT `player_id` AS `average_player_id`".
  "    , name ".
  "    , (SELECT AVG(`rating`) FROM `sternberg_matchrating` WHERE `player_id`=`average_player_id`) AS `average` ".
  "  FROM sternberg_player " .
  " WHERE club_id = " . $_REQUEST[club] . " ";
$rsPlayerList=DBExecuteRS($strSQL);
while ($rowPlayerList = DBFetchArray($rsPlayerList)) {
    $i++;
    ?>
<tr>
<td>
<a href="viewPlayer.php?id=<?=$rowPlayerList["average_player_id"];?>">
<?=$rowPlayerList["name"];?>
    </a>
</td>
<td>
<?=$rowPlayerList["average"]?round($rowPlayerList["average"],2):"0";?>
</td>
</tr>
<?   
}//end while
?>
</table>

På forhånd tak
