Populating a JavaFX TableView from an RxJava Observable>

Question

I have an Observable<List<T>> that I want to display with a TableView<T>.

It seems as though there should be a library function in JavaFx to convert an RxJava Observable<List<T>> into a JavaFx ObservableList<T>, but if there is, I can't find it (though there's lots of support in RxJavaFx for going the other way).

Do I need to write my own ObservableListBase<T> implementation and my own implementation of ListChangeListener.Change, or is there a better way?

Should I just replace the items wholesale?

TableView<T> table = ...
Observable<List<T>> observable = ...

observable
  .observeOn(JavaFxScheduler.platform())
  .subscribe(updatedList -> {
    ObservableList<T> items = table.getItems();
    items.setAll(updatedList);
  });
