Hi,
http://webix.com/snippet/7e251733
if you look at above example, 20 or 30 rows per rowspan works well. But when I try to have 70 rows to span and try to scroll down, cells are not rendered correctly. I will have big data (at least 5000 rows x 30 columns), and I plan to have big rowspans, at least 300 rows. Can you please help me on this, am I doing something wrong?
Thanks…
