title: Woocommerce admin order details shipping price with TAX
body: <p>I needed to add product price with tax in woocommerce admin order details and this code works very well:</p>
  <pre><code>/**
       * Display tax included price under order details page.
       */
      function ap_item_total_header() {
          echo '&lt;th width=100%;&quot;&gt;' . esc_html__( 'Cena produktu brutto', 'item-total-for-wc' ) . wc_help_tip( esc_html__( '', 'item-total-for-wc' ) ) . '&lt;/th&gt;';
      }
      add_action( 'woocommerce_admin_order_item_headers', 'ap_item_total_header' );
  
      /**
       * Display the total tax for a line item.
       *
       * @param object $product Product object.
       */
      function ap_display_item_total( $product ) {
          global $post;
          if ( ! is_int( $thepostid ) ) {
              $thepostid = $post-&gt;ID;
          }
          $order       = wc_get_order( $thepostid );
          $order_items = $order-&gt;get_items();
          foreach ( $order-&gt;get_items() as $item_id =&gt; $item ) {
              if ( $item['product_id'] === $product-&gt;id ) {
                  $price = ($item['total_tax'] + $item['total']) / $item['quantity'] ;
              }
          }
          $test  = '&lt;td class=&quot;item_total_cost&quot;&gt;';
          $test .= '&lt;div class=&quot;view&quot;&gt;';
          $test .= wc_price( $price, array( 'currency' =&gt; $order-&gt;get_currency() ) );
          $test .= '&lt;/span&gt;&lt;/div&gt;&lt;/td&gt;';
          echo $test;
      }
      add_action( 'woocommerce_admin_order_item_values', 'ap_display_item_total' );
  }
  </code></pre>
  <p>But under product we have shipping - and price is 0, then price without tax, next tax. I need to have shipping price included tax.</p>
