Are you sure you want to use setOnScroll to listen to scroll events rather than set the value of the scroll bar position via the tableView.scrollTo api (which I would recommend) or the scrollBar.setValue() api?
for (Node n: table.lookupAll(".scroll-bar")) {
  if (n instanceof ScrollBar) {
    ScrollBar bar = (ScrollBar) n;
    System.out.println(bar.getOrientation() + ": range " + bar.getMin() + " => " + bar.getMax() + ", value " + bar.getValue());
      if (bar.getOrientation().equals(Orientation.VERTICAL)) {
      bar.setValue(0.5);
}If you did really, really want to use setOnScroll, then you could do something like this:
Node flow = table.lookup("VirtualFlow");
if (flow != null) {
  final EventHandler<? super ScrollEvent> originalScrollHandler = flow.getOnScroll();
  flow.setOnScroll(new EventHandler<ScrollEvent>() {
    @Override public void handle(ScrollEvent event) {
      System.out.println(event);
      originalScrollHandler.handle(event);
}  Though you would be better off just using an eventfilter rather than using the strange lookup and setOnScroll chaining method in the above code.
table.addEventFilter(ScrollEvent.ANY, new EventHandler<ScrollEvent>() {
  @Override public void handle(ScrollEvent event) {
    System.out.println(event);
    // uncomment if you don't want the default table scroll events processing to take effect.
    //event.consume();
});
