title: Display a product custom field value in WooCommerce cart and checkout table
body: <p>In WooCommerce and I have added a custom field "description" for each product.
  I was able to find a way to show both, the label name and the value:</p>
  
  <pre><code>add_filter( 'woocommerce_add_cart_item_data', 'save_days_field', 10, 2 );
  function save_days_field( $cart_item_data, $product_id ) {
      $special_item = get_post_meta( $product_id , 'description',true );
  
      if(!empty($special_item)) {
          $cart_item_data[ 'description' ] = $special_item;
  
          // below statement make sure every add to cart action as unique line item
          $cart_item_data['unique_key'] = md5( microtime().rand() );
          WC()-&gt;session-&gt;set( 'description', $special_item );
      }
      return $cart_item_data;
  }
  
  // Render meta on cart and checkout
  add_filter( 'woocommerce_get_item_data','rendering_meta_field_on_cart_and_checkout', 10, 2 );
  function rendering_meta_field_on_cart_and_checkout( $cart_item_data, $cart_item ) {
      if( isset( $cart_item['description'] ) ) {
          $cart_item_data[] = array( "name" =&gt; __( "Description", "woocommerce" ), "value" =&gt; $cart_item['description'] );
      }
      return $cart_item_data;
  }
  </code></pre>
  
  <p>Now I need to display ONLY the value (not the label name "Description") of this custom field <strong>in the cart and checkout table</strong>. I need to display with <code>&lt;small&gt;</code>, like the attribute I am displaying with this code:</p>
  
  <pre><code>add_filter('woocommerce_cart_item_name', 'wp_woo_cart_attributes', 10, 2);
  function wp_woo_cart_attributes($cart_item, $cart_item_key){
      $productId = $cart_item_key['product_id'];
      $product = wc_get_product($productId);
      $taxonomy = 'pa_color';
      $value = $product-&gt;get_attribute($taxonomy);
  
      if ($value) {
          $label = get_taxonomy($taxonomy)-&gt;labels-&gt;singular_name;
          $cart_item .= "&lt;small&gt;$value&lt;/small&gt;";
      }
      return $cart_item;
  }
  </code></pre>
  
  <p>How can I make it for this custom field, displaying the value only? </p>
