Not sure if you can re-render cells in isolation, but you should be able to get it to redraw individual rows rather than the whole table. Try replacing the updated item with itself in the DataProvider (e.g. if using a ListDataProvider by calling set(index, item) on the underlying List, or if using an AsyncDataProvider by calling updateRowData on the dataprovider passing in a singleton list containing just the updated item). Alternatively you can try calling setRowData() on the DataGrid itself.
