Table style in doc does not correspond to real

[Claus1]

Description

In q-table I see tables look this:

But in corresponding Codepen https://codepen.io/pen?&editors=111 and on my computer it looks different:

As you scroll bars are very different. Can you please explain to me and to users, how to connect nice looking scrollbars to table, which are already in quasar as I see in q-tree, documentation, but not work.
Why nice looking scrollbars works by default in q-tree, not in table.
