我需要对显示表中的一列求和。我的问题：如何对已从其他列计算数据的表列求和？我需要使用javascript来做到这一点吗？我想在相关列的底部显示总数。提前感谢您的建议。

我当前计算的数据示例：

echo round(($r->price_sold - $r->shipping - $r->tax - $r->fees) * $r->commission_rate / 100,2);



    $query = "
SELECT *
  FROM jos_data_Used_Gear
  ORDER BY client_name ASC  
  LIMIT 0, 100;
";

$db->setQuery($query);
$url = $db->loadObjectList();


echo '<table id="consignment-table" border="0" align="center" width="3000px">'; 
echo '<tr class="consignment-header"><th class="consignment-client">Client</th>'; 
echo '<th class="consignment-title">Item Name</th>'; 
echo '<th class="consignment-saleprice">Price Sold</th>'; 
echo '<th class="consignment-saleprice">Tax</th>';
echo '<th class="consignment-saleprice">Shipping</th>';
echo '<th class="consignment-saleprice">Service Fee</th>';
echo '<th class="consignment-saleprice">Commission</th>';
echo '<th class="consignment-saleprice">Due Client</th>'; 

if(count($url)) {
  foreach($url as $r) {
    echo '<tr><td nowrap="nowrap">';
    echo $r->client_name;
    echo '</td><td nowrap="nowrap">'; 
    echo $r->item_title;
    echo '</td><td class="currency" nowrap="nowrap">'; 
    echo "&#36;";
    echo $r->price_sold;
    echo '</td><td nowrap="nowrap">'; 
    echo "&#36;";
    echo $r->tax;
    echo '</td><td class="currency" nowrap="nowrap">'; 
    echo "&#36;";
    echo $r->shipping;
    echo '</td><td nowrap="nowrap">'; 
    echo "&#36;";
    echo $r->fees;
    echo '</td><td nowrap="nowrap">'; 
    echo round(($r->price_sold - $r->shipping - $r->tax - $r->fees) * $r->commission_rate / 100,2);
    echo '</td><td class="currency" nowrap="nowrap">'; 
    echo "&#36;";
    echo round(($r->price_sold - $r->fees - $r->tax - $r->shipping) - (($r->price_sold - $r->fees - $r->tax - $r->shipping) * $r->commission_rate / 100) ,2);
    echo "</td></tr>";

  } 
}

echo '</table>';
