Sorting has been added on some columns with version 0.6.3. But it's a pretty rough version and it does not indicate which ones can be sorted, and if the current sort is ascending or descending.
Describe the solution you'd like
Add an arrow on sortable arrows. The arrow direction must be set accordingly to the sort order (ascending or descending).
Describe alternatives you've considered
An arrow but with no changing direction.
