I have a page with table.
I want insert button in page (not table), which will change view of table to groupped and without groupped.
How can i do this?
p.s. I found this topic Sort / group table with external controls by @Paul_Danyliuk, but in second action i want to ungroup table for normal (default) view. I think i may duplicate column for grouping, but i will use view of this table in another page, and because of this i dont want duplicate column
