When both properties are 'true', the dragcolumn doesn't work on the grid datatable.
Please refer to this thread, where you have posted the same question: https://forum.webix.com/discussion/37068/drag-and-drop-and-areaselect-in-datatable-causing-dropped-row-to-move-last#latest
In short, both of these properties are incompatible, you can't expose these two actions simultaneously in the config.
Could you please clarify your use-case and how it should work?
