Action on clicking header in data grid

Questions
1

Is it possible to get an event/notification/action from a user clicking on a column header in a data grid component?

2

there is only the onSort handler that is called when cliking the header for sorting

3

That would require the user to select the sort on the header; is it possible to introduce an event on clicking on the header?
