Dhtmlx Grid Split incompatible problem

I found this description in “http://docs.dhtmlx.com/doku.php?id=dhtmlxgrid:columns_manipulation

Note: this method should be called when the grid is initialized. This mode is incompatible with some grid functionality.

What’s the “some grid functionality”? Is it possible to give a list of “some grid functionality” which does not work with split? Because i found the split doesnot work with “onCellMarked” event.
