The easiest way to install this is using:
bower install https://github.com/isocra/TableDnD.git
This will install the TableDnD plugin into your bower components as well as installing jQuery which it depends on.
Documentation will go here, for now, go to Isocra's TableDnD Blog posting
You can also play and experiment with TableDnD using this jsFiddle (it's not complete yet, the ajax callbacks don't work--not surprisingly--but it's still useful for testing and exploring).
