Why the use of HTML Tables?

Hi!

I am a quite experienced Worodpress designer/developer but havnt worked so much with Woocommerce. Now I have a project where a am about to build a hightly customized webshop using Woocommerce.

The first thing that struck me was that Woocommerce still (in 2018) uses old fashioned html tables to structure different kind of web content which makes customezied styling much more difficult, limiting and time consuming. Why?

Today there are css tools like flex-boxes and grids which are much more flexible making custom style customization a breeze compared to the old and outdated tables.

Is there a way to get the web content that different functions generate without the terrible table structures or are I stuck with them and just have to try styling them the best way possible?
