How to show only one record in order grid for the same Order ID for parent configurable product and child simple product?

Question

In order grid, two records with same Order ID are shown when the product is configurable product that has child product so-called simple product. I only want child product (simple product). I don't want parent product (configurable product). But the child simple product record only shows zero in Total column while the parent configurable product record shows total amount in Total column . What I want to get is the child simple product with the Total amount extracted from parent configurable product.

Naing,add parent id filter

$collection = Mage::getModel('sales/order_item')->getCollection()

                       ->addFieldToSelect(array('order_id','sku','name','qty_ordered','product_id','product_options','row_total'))

                       //->setOrder('main_table.order_id', 'desc');
                       ->setOrder('main_table.created_at', 'desc');

        //  $collection->getSelect()->group('main_table.order_id');

To

$collection = Mage::getModel('sales/order_item')->getCollection()
  ->addFieldToSelect(array('order_id','sku','name','qty_ordered','product_id','product_options','row_total'))
    ->addFieldToFilter('parent_item_id',array(
        'null' => true,
        ))->setOrder('main_table.created_at', 'desc');
