Is it possible to select and drag a only 1 particular data in datatable without dragging whole record ?
You can configure the visual element that appears during drag-n-drop, so it can contain the cell text only.

Also, in onDrop handler you can access the info about the exact cell, where d-n-d was started, and based on that produce some custom drop behavior ( for example move the value for the dragged cell only )
