[jira] [Updated] (ARROW-12739) [C++] Function to combine Arrays row-wise into ListArray

["Ian Cook (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARROW-12739?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ian Cook updated ARROW-12739:
-----------------------------
    Description: 
Add a function that would take 2+ Arrays and combine/transpose them rowwise into a ListArray. For example:
 Input:
{code}
Array<string>        Array<string>
[                    [
  "foo",               "bar",
  "push"               "pop"
]                    ]
 {code}


 Output:
{code}
ListArray<list<item: string>>
[
  ["foo","bar"],
  ["push","pop"]
]
{code}
 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).
