When using custom template and set columns visiblity to false its still visible (data rows are visible but column header is hidden). Note that this appears only when visibility is false on initialization, if column is hidden afterward from column chooser component works. Changing visiblity afterward by code is not tested.
Can be workarounded by setting visible true but calling hideColumn rightAfter creating grid.
