follow up again on adding row with different row types

sir, you suggested me to use setColExcelTypes and setRowExcelTypes in changing the type of rows and cells on the fly. However, I am only using a trial version. Are there any alternatives for it?

The next will work simlar to setRowExcelTypes, and can be applied in standard version

mygrid.forEachCell(ID,function(ed){
    var t=ed.getValue();
    ed.cell._cellType=TYPE;
    ed.setValue(t);
});


where ID - ID of row
          TYPE  - excell type

setting _cellType  property change type of editor, two other lines reset value of cell, so it will be correctly formatted.
