Hi
I still think that it should work, even you don't have to group it (I don't
like this future and I don't use it actually), but creating a colum called
"group" or "header" should really help. example
group data
A 1
A 2
B 1
B 3
B 5
etc
so when you sort by the colum A (group) all data are "attached" to the
group, so I think it should solve the problem you have
