在drupal中使用theme_table()创建可排序表格

function package_coupon_list() {
    $head = array(
        array('data' => t('Coupon'), 'field' => 'coupon', 'sort' => 'asc'),
        array('data' => t('Type of Discount')),
        array('data' => t('Created'), 'field' => 'created'),
        array('data' => t('Expire'), 'field' => 'expire'),
        array('data' => t('Status'), 'field' => 'used'),
        array('data' => t('Used by')),
    );
 
      $sql = "SELECT * FROM package_coupon" . tablesort_sql($head);
 
       $result = db_query($sql);
 
      while ($coupon = db_fetch_object($result)) {
        $rows[] = array(
            array('data' => _coupon_format($coupon->coupon)),
            array('data' => ($coupon->operator == '%' ? "{$coupon->operand}% discount" : "\${$coupon->operator}{$coupon->operand} discount")),
            array('data' => format_date($coupon->created, 'small')),
            array('data' => format_date($coupon->expire, 'small')),
            array('data' => $coupon->used . ' left'),
            array('data' => ($coupon->user_by == '') ? 'None' : $coupon->user_by),
        );
      }
 
    return theme_table($head, $rows);
}
