how to change a default read only cell to Editable cell

i am using mygrid.setCellExcellType(rowId,cellIndex,type);
i want to change 2nd row,5th coulmn to editable cell at run-time(dynamically) .
But the above api does not work.
is there any way or api to make a read-only(ro) cell to editable cell

setCellExcellType method is available in PRO version only.

Is there another way to dynamically change a cell to Editable without the PRO version?

There is no way to change cell type dynamically in free version.
In free version you can set cell type from xml using “type” attribute of the cell tag:

<cell type="ed">Cell value</cell>
