Closing `</div>` is added for tables that do not use `<table>`

Will also add a closing </div> to tables that were not targeted by <table>. As a result, closing </div>s might be injected where they shouldn't.

Possible solution is to target <table rather than <table so all tables are affected the same way. Users won't have a way to disable it then. That's not necessarily bad, but the option should still exist to add extra classes.
