             Summary: [C++] Function to combine Arrays row-wise into ListArray
                 Key: ARROW-12739
                 URL: https://issues.apache.org/jira/browse/ARROW-12739
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Ian Cook


Add a function that would take 2+ Arrays and combine/transpose them rowwise into a ListArray. For example:
Input:
Array<string>        Array<string>
[                    [
  "foo",               "bar",
  "push"               "pop"
]                    ]
Output:
ListArray<list<item: string>>
[
  ["foo","bar"],
  ["push","pop"]
]
This is similar to the StructArray constructor which takes a list of Arrays and names (but in this case it would only need to take a list of Arrays).
