I've looked around on Google and the WooCommerce docs, but I feel like I'm not using the correct terminology here. Hopefully one of you can point me in the right direction.
I need to add a column to the cart table (not sure what it's actually called) that is populated on checkout pages, for example on the checkout/order-pay/ endpoint.
You can see an example here:
I've looked in various templates for the order, review-order, checkout, etc, but to no avail. Where is this table generated in the source code? I assume that it's part of some kind of array that gets looped through?
