If you are using table plugins, I am replying on the presumption that this is for on page content and not a woocommerce product compare solution. The only way I have got around this is;

a) as you say scrollable tables which are not the best (tablepress does have a plugin for this I can drag it out if you need) or
b) using wp bakery and table press and physically seperating the tables on mobile to have more than one. I hid the main table and show the multiple tables on mobile under column settings.

Here is an example (it will show the break if you resize the browser)
