Hi, I am looking for a feature that would select from a table with k1 a k1 b k1 c k2 a k3 b k3 c something like k1 a b c k2 a k3 b c (Just all elements next to each other, with a space in between) or perhaps an array output k1 {a,b,c] k2 {a} k3 {b,c} If such an operator exists, would there be a "remove duplicates" option?
