That table is in the database that you can access with your PHPMyAdmin. But I'm talking about adding that code in the code of the email.
We could have just told you that it is not possible and to just fill a feature request, but we actually went the extra mile and gave you a solution where you just have to copy/paste text, far from having to learn coding. Also, the information is already in the order details page for which there is a link in the order email so it's not like the customer doesn't have a way to see that if he wants to.
