Answer 1

As this problem still isn't really fixed [JavaFX 8u11] & because the need of an account to view the JIRA thread, i will add the current workarround here. This solution works flawlessly for me, but be aware that it is depraced, which means that the method could be removed with the next update suddenly.

With a TableColumn variable like "tableC" you can do following:

tableC.impl_setReorderable(false);
