I sent my whole code earlier. If you did not get it, please let me know.
Update:
I tried the removeColumn() method, but I still get the same results. It is
doing the same as the setColumn. I verified this with the getViewColumns()
method.
I also am able to duplicate columns. If I do this:
view.setColumns([0,1,2,2])
It does actually produce column 2 twice which makes column 3 not visible
any longer. It also updates the legend. I have attached a photo of this
behavior.
