Datatable scrolling with Javascript

Hi,
I have a datatable like in the example here: http://webix.com/snippet/671c8328
Is there a way to scroll the table up and down using javascript commands? I have to write automated selenium tests and they needs to access results that are further down in the table. Unfortunately Selenium has no way of using a Scrollbar, thats why i tought maybe i can scroll the table using javascript (which i then call from selenium).
Thanks,
Marc

try this snippet: http://webix.com/snippet/4f8aca4e

used methods ui.datatable:

showCell(); // to scroll for this cell

and

select() // for selecting this row (for styling)

Thanks!
