I chage the query on AdminOrdersController.php Full Link is >>> myshop/controllers/admin/AdminOrdersController.php $this->_select = ' od.product_name AS products_zee, /* This is the main thing which I changed */ a.id_currency, a.id_order AS id_pdf, CONCAT(LEFT(c.`firstname`, 1), \'. \', c.`lastname`) AS `customer`, osl.`name` AS `osname`, os.`color`, IF((SELECT COUNT(so.id_order) FROM `'._DB_PREFIX_.'orders` so WHERE so.id_customer = a.id_customer) > 1, 0, 1) as new'; $this->_join = ' LEFT JOIN `'._DB_PREFIX_.'order_detail` od ON (od.`id_order` = a.`id_order`) LEFT JOIN `'._DB_PREFIX_.'customer` c ON (c.`id_customer` = a.`id_customer`) LEFT JOIN `'._DB_PREFIX_.'address` addr ON (a.`id_address_delivery` = addr.`id_address`) LEFT JOIN `'._DB_PREFIX_.'order_state` os ON (os.`id_order_state` = a.`current_state`) LEFT JOIN `'._DB_PREFIX_.'order_state_lang` osl ON (os.`id_order_state` = osl.`id_order_state` AND osl.`id_lang` = '.(int)$this->context->language->id.')'; $this->_orderBy = 'id_order'; $this->_orderWay = 'DESC'; After that I add array after this code
'reference' => array( 'title' => $this->l('Reference'), 'align' => 'center', 'width' => 65 ), /* This is my Product Name */ 'products_zee' => array( 'title' => $this->l('Products'), 'align' => 'center', 'width' => 85 ),
