[Feature Request]: Allow reordering of the query result columns

### Feature Description

It would be helpful if the columns of a result table could be dragged to the left or right. This would help with comparing information between distant columns.

### Problem and Motivation

I could always change a query and re-run it to move columns around, but there are times when I do not want to refresh the result set. At other times I may want to compare four of five different columns. I may need to scroll back and forth to view desired information. It would be easier to be able to put columns in a desired order and then alter the order as necessary so that relevant information is always next to what it is related to.

The requested change is in the Query results panel; start by locating the result-table implementation and its existing column interaction behavior. Add drag-based column reordering without refreshing the result set, and verify that columns can be moved left or right and remain in the selected order.
