How to clear column sorting in Grid from the browser

I know you can do grid.clearSortOrder() in the code but as a user seeing a grid in my web browser how do I clear the sorting order in the grid?

I think you need to e.g. add button in your UI and call grid.clearSortOrder() in the click listenerer.

There’s no way to do it within the GUI without an outside action? As in when you click the column header it goes from ascending, then descending, then none?
