On the DevExpress form it is written that it seems impossible.
But yesterday for some reason I did it. That is, I put groupindex:=0 on the column GridMode:=true , and the column itself was not sorted: table
AAAA AAAA BBBB BBBB AAAA AAAA was turning into
AAAA+ BBBB+ AAAA+ And today I can not repeat.
