Table row drag&drop to re-order

We have a jira like backlog feature, the entries are rows in a table.

We need to be able to change the order of the rows by drag&drop: Drag 1 row above another.

We had to add drag drop event listeners to the table cells

Row1: [cell 1 drag handle] | [cell 2 drop listener]
Row2: [cell 1 drag handle] | [cell 2 drop listener]
Row3: [cell 1 drag handle] | [cel l2 drop listener]

Due to the way this component works, we could not dnd on the whole table row, we had to listen on the individual cell.

Would be nice to be able to drag and drop a table row onto a whole other table row and have the native drag and drop functionality just baked into the table component.
