Saving user created list to account

Hello guys i recently got into PHP and I am creating a basic account DB driven php website that lets you create your own groceries list, it already shows the list from the products Table but im not sure how should i go about saving the list they created to their accounts so they can see it anytime, i was thinking creating a new table for each list but that doesnt sound good. Any ideas?

I have the users table with userid,login,pw and name. And the products table of course
