Adding "Price" field to Ubercart cart page

On the /cart page of Ubercart store, you can usually see such fields:

That's total price per row, and amount of products per row.

For a customer project, I wanted to add single item price to this page, to make it look like this:

After some digging into Ubercart code, that task was solved in ~10 lines (put these lines in your module):    t('Price'),     'weight' => 2.5,   );    foreach (element_children($table) as $key) {     if (empty($table[$key]['nid']['#value'])) continue;        // This db-expensive node_load call can be easily avoided by using        // single SQL select. But,        // that's not so important if visitor usually adds 1-5 products to cart.       $n = node_load($table[$key]['nid']['#value']);       $p = uc_price($n -> sell_price, array());     // Add data to our new column       $table[$key]['price_item'] = array(          '#value' => $p,           '#cell_attributes' => array('class' =>'price-item')       );       }}   ?>

That's so easy because Ubercart uses Tapir table builder for most important tables (like cart page) and we can use Drupal hooks to extend them!
