Transformation:
You can apply the following transforms in the following order. Note that the column names must be different from the transform name, which is a reserved word.

Results:
For display purposes, the results table has been broken down into three separate sets of columns.
Column set 1:
| Item | ArrayA | ArrayB | concat2 | intersection2 |
|---|
| Item1 | | ["1","2","3"] | ["A","B","C","1","2","3"] | [ ] |
| Item2 | ["A","B"] | ["A","B","C"] | ["A","B","A","B","C"] | ["A","B"] |
| Item3 | ["D","E","F"] | ["4","5","6"] | ["D","E","F","4","5","6"] | [ ] |
Column set 2:
| Item | cross2 |
|---|
| Item1 | [["A","1"],["A","2"],["A","3"],["B","1"],["B","2"],["B","3"],["C","1"],["C","2"],["C","3"]] |
| Item2 | [["A","A"],["A","B"],["A","C"],["B","A"],["B","B"],["B","C"]] |
| Item3 | [["D","4"],["D","5"],["D","6"],["E","4"],["E","5"],["E","6"], ["F","4"],["F","5"],["F","6"]] |
Column set 3:
