Implement an alternative to Scrollable.ensureVisible for the table

[NikolayNIK]

Yeah, I've taken a look at the implementation of the Scrollable.ensureVisible and it doesn't look like it would work for the horizontal scrolling in this library.

Basically, it correctly works for the vertical Scrollable than proceeds to make sure that vertical Scrollable is visible from the horizontal one (which it always is) and promptly gives up.

I'll create a feature issue for a some kind of different implementation on the side of the library. Let me know if I've missed anything.
