             Summary: [Python] Add sort helper method to StructArray
                 Key: ARROW-14656
                 URL: https://issues.apache.org/jira/browse/ARROW-14656
             Project: Apache Arrow
          Issue Type: Sub-task
            Reporter: Alessandro Molina


It's usually a common need to sort the results of an aggregation.

The group_by method of tables returns a {{StructArray}} to provide multiple aggregations at once. Given that we don't support directly sorting a {{StructArray}} it means a few lines of code are necessary for a simple sort operation. It would be helpful to provide an helper method in {{StructArray}} that provides a one line solution for most simple cases.
