Table embedded inside another table

[ghost]

Awesome piece of code, I could not even begin to understand it.
However, I find I cannot get it to work properly if tableDragger() is passed a table that is embedded inside another table. The rows jump to the top of the whole window while they are being dragged, and cannot be moved to a new position.
I'm after creating a large table with draggable rows at different levels.
Any reason that would not work?
