cell data to clipboard

Can I use the tabletools zeroclipboard integration to copy stuff to the system clipboard, without using a copy button ?
What I want is to copy the cell value to clipboard when clicking on that cell.

I've already been able to grab the cell data in js var iId.
My tabletools are set up properly.

currently I'm using the nasty solution :

window.prompt ("Copy to clipboard: Ctrl+C, Enter", iId);
