我想你是这个意思，我希望它对u 有用

<?php
 $dynamicListBody = "";
$sql = mysql_query("SELECT * FROM products WHERE category='Body' ORDER BY id ASC");

    $i=0;
    while($row = mysql_fetch_array($sql)){
             $id = $row["id"];

         $price = $row["price"];
         $date_added = strftime("%b %d, %Y", strtotime($row["date_added"]));
         $dynamicListBody .= '
         <table width="95%">';
         // to Display 4 cell and n row
