When you resize a column, the horizontal scrollBar gets back to the left, therefore it's quite impossible to resize the columns.

To reproduce:
-Take the TableViewSample (http://docs.oracle.com/javafx/2/ui_controls/TableViewSample.java.html)
-Enlarge the last column to the right, so that the header "Email" is not visible.
-Horizontal Scroll Bar is not showing (why?), so click on a header to enable sorting. Now you have the scroll bar.
-Click the scroll Bar and go to the right.
-Try to resize a column, you'll see that the scrollBar goes back to its position.
