TableView将不会填充

Question

我正在为Uni项目创建一个Cinema系统。我已经在JavaFXML中创建了一个Tableview，但是无法用数据填充它。我不确定为什么。

Main.java（CinemaSystem.java）-这是项目的主类。

@Override
public void start(Stage primaryStage) throws Exception{
    Parent root = FXMLLoader.load(getClass().getResource("home.fxml"));
    primaryStage.setScene(new Scene(root));
    //Set Stage as Borderless
    primaryStage.initStyle(StageStyle.UNDECORATED);

    //Make window draggable
    root.setOnMousePressed(event -> {
        x = event.getSceneX();
        y = event.getSceneY();
    });
    root.setOnMouseDragged(event -> {

        primaryStage.setX(event.getScreenX() - x);
        primaryStage.setY(event.getScreenY() - y);
    });

    primaryStage.show();



}


public static void main(String[] args) {
    launch(args);
}}

CinemaController.java-这是home.fxml文件的控制器。

public class CinemaController {

public abstract class FilmController implements Initializable {

    //Configure the table
    @FXML
    private TableView<Films> tableView;
    @FXML
    private TableColumn<Films, String> filmNameColumn;
    @FXML
    private TableColumn<Films, String> filmYearColumn;
    @FXML
    private TableColumn<Films, String> filmAgeColumn;
    @FXML
    private TableColumn<Films, String> filmTheatreColumn;
    @FXML
    private TableColumn<Films, LocalDate> filmDateColumn;


    public void initialize(URL url, ResourceBundle rb) {
        //set up columns in the table
        filmNameColumn.setCellValueFactory(new PropertyValueFactory<Films, String>("FilmName"));
        filmYearColumn.setCellValueFactory(new PropertyValueFactory<Films, String>("Year"));
        filmAgeColumn.setCellValueFactory(new PropertyValueFactory<Films, String>("AgeRating"));
        filmTheatreColumn.setCellValueFactory(new PropertyValueFactory<Films, String>("Theatre"));
        filmDateColumn.setCellValueFactory(new PropertyValueFactory<Films, LocalDate>("DateTime"));

        //load dummy data
        tableView.setItems(getFilms());

    }

    //Return an ObservableList of Objects

    public ObservableList<Films> getFilms() {

        ObservableList<Films> Films = FXCollections.observableArrayList();
        Films.add(new Films("Test", "2000", "18+", "12", LocalDate.of(2019, Month.MARCH, 25)));

        return Films;

    }
}}

home.fxml-在此文件中，TableView具有以下内容：

      <TableView fx:id="tableView" layoutX="268.0" layoutY="115.0" prefHeight="480.0" prefWidth="635.0">
     <columns>
        <TableColumn fx:id="filmNameColumn" prefWidth="175.0" text="Film Name" />
        <TableColumn fx:id="filmYearColumn" minWidth="0.0" prefWidth="109.0" text="Film Year" />
        <TableColumn fx:id="filmAgeColumn" minWidth="3.0" prefWidth="98.0" text="Age Rating" />
        <TableColumn fx:id="filmTheatreColumn" minWidth="0.0" prefWidth="111.0" text="Theatre" />
        <TableColumn fx:id="filmDateColumn" prefWidth="141.0" text="Date / Time" />
     </columns>
  </TableView>

当我运行该程序时，它在表视图中没有显示任何数据，我不确定为什么。任何帮助将是巨大的！谢谢。
