Checkout subtotal section

Hello, on the checkout subtotal section (.woocommerce-shipping-totals) the table has both the left and right columns but the width is not appropriate to the content. I would like to make the <th> thinner and the <td> wider.

If you go to our checkout and look at it, you can see the labels for the shipping methods get squashed to new lines whereas the <th> is wider but just has the label "Shipping".

Hope that makes sense.

Thanks
