If you have defined your application class to be the controller in the FXML file, JavaFX will, if I remember correctly, create a new instance of your application class and use the new instance as a controller. Thus, your existing application class still has null for the table.

You can however define the controller programmatically in your application class to use your own instance:

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("example.fxml"));
fxmlLoader.setController(this);
Parent root = (Parent)fxmlLoader.load();
