I have a problem with export to excel when treelist contains columns in group
See Dojo 1
1. Last name is second column in browser, however in excel it is last one.
The problem is not so big if data corresponded to header, but header and data do not match!!
2. Group is not a merged column
In certain scenarios we get completely broken file. Dojo 2.
Excel offers to restore file, but after restore, header is even more broken than in first scenario (see attachments)
I tested it in chrome with jszip 2.4.0, 3.1.5, 3.2.0
Any possibilities to fix it?
