title: How add column shipping cost to order list in Prestashop 1.7?
body: <p>I would like add new column "Shipping cost" to order list in backoffice of Prestashop 1.7. I read a lot of tutorials about adding new column, but nowhere is advice about shipping cost.</p>
  
  <p>Another solution should be, if the shipping cost will be shown directly in field with order total price? Eg.: 150 USD (2 USD) - where 2 USD are shipping cost.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>SOLVED:
  in file: controllers/admin/AdminOrdersControler.php
  add under (line about 110): <code>$this-&gt;fields_list = array_merge($this-&gt;fields_list, array(</code></p>
  
  <p>this code:    </p>
  
  <pre><code>'total_shipping' =&gt; array(
          'title' =&gt; $this-&gt;l('Shipping'),
          'filter_key' =&gt; 'a!total_shipping',
          'type' =&gt; 'price',
          'currency' =&gt; true,   
          'callback' =&gt; 'setOrderCurrency' 
      ),
  </code></pre>
  
  <p>and add above line 200: <code>public static function setOrderCurrency($echo, $tr)</code></p>
  
  <p>this code:</p>
  
  <pre><code>public function displayTotal_shipping($value) {
       return Tools::ps_round($value, 0);
  }
  </code></pre>
