Cloud inserts the table that takes the whole width of the page
while i need to insert a small table (something that could take 1/3 of the width of the page for example).
I have a page with lots of tables and the size of them resets every time i edit a page. Do you know how to avoid that?

Since the new editor was released, when we add tables on a page there is no option to add a custom width. It's possible to change the size of the columns, but not the entire table.
There is a feature request suggesting the implementation of this ability:
