Javafx : Restrict Column rearrangement on drag and drop -

in tree table view, can re-arrange columns dragging column headers. want restrict user dragging first column alone. means first column should first column time.

is possible?

thanks in advance.

this simple example storing column arrangement in temporary list , when ever trying move or replace first column resetting column arrangement.

!change.getlist().get(0).equals(col1) 

checks if col1 still @ first location after change. if not, replace old list.
