Cart page – shipping method columns width

Hello,

On the woocommerce cart page you can choose different shipping methods. It looks to me, that there are two columns (th & td I guess?). How can I change proportions of them, so that the left column is 20% width vs right column being 80%?
I wish that descripion of the shipping methods on the right be more readable, and not so packed.

I tried adding custom CSS style, however it does not work:

.woocommerce .cart-collaterals .cart_totals table td,
.woocommerce-page .cart-collaterals .cart_totals table td {
  width: auto;
}

I am using basic Twenty Seventeen theme + Elementor Pro visual builder.

Thank you for your time and support.
