Dynamically adding columns to a Tree Table

Is there a way to programatically add columns to a tree table, say, on a button press (which I can later load data into)?

I can see methods to add views or change attributes, but I’m not sure how to achieve something like this.

Thanks!

you can access the column’s configuration like grid.config.columns - just add or remove anything there and call grid.refreshColumns
