Table | Scroll to a non visible row

How can i make a row become visible?

I have 100 rows. The first 20 are visible at the moment.

then i want programmatically select a row (like row number 80) → This works
But then i also want that this row become visible?

How can i do this?

Thanks!!

Sorry, my mistake:

works fine like:

    table.setValue(80);
    table.setCurrentPageFirstItemIndex(80);
