Hello,

I have added icons in tree view to perform some actions and i want to show header / label to these buttons. For example, I have two icons on tree view and its header title is empty. So i want to add a single heading for these icons which will be "Action" for eg. for all the records like other fields heading. 

I have tried a link for this and exactly i want the same in my case but didn't worked for me. here is the link:
