I have a component that is Ext.grid.Tree and the TreeStore, I want to make the first column locked but seem the Ext.grid.Tree is not supported. I don't want to change to another component like Ext.grid.locked.Grid or switch to the Modern because it impacted to my design and the functionalities. Here is my fiddle, please advise!
