DhtmlxGrid export to Excel except first column

I’ve used online export services to export dhtmlxgrid to excel. I’m using below code:

//exporting to Excel by using the online export service

It is working fine. There is no problem.
Then i try to export grid except first column to excel. But i can’t make this work as i expected.
Is it possible?
I’ve followed this url:http://docs.dhtmlx.com/grid__data_export.html#errorshandlingandlogging

Please, try to hide your column before export to excel using the setColumnHidden() method:
