Descriptions were added in the 4.0 update of Table Rate Shipping for WooCommerce. Every row has the ability to set a different description, which can either override a previous description or add to it. This text will then appear in addition to the shipping title and price in the cart and checkout pages, as well as the order summary once completed.
