Is ZeroClipboard necessary if not using "copy" button?

Based on the description of Zero Clipboard at https://github.com/jonrohan/ZeroClipboard, it seems that this functionality--and the flash file that powers it--is used for providing the TableTools "copy" button functionality. If "copy" is not needed, is ZeroClipboard.js still necessary?

I have a working example of TableTools running at http://jsfiddle.net/jhfrench/6b74w/68/. When I remove the "copy" button, and the custom path to SWF file (see http://jsfiddle.net/jhfrench/6b74w/72/), DataTables breaks ("Uncaught ReferenceError: ZeroClipboard_TableTools is not defined ").
