在TableView中沒有列出現的JavaFX

Question

我想填入數據ITO的TableView但不知何故，不顯示任何

此，我用它作爲一種創建的ArrayList類：

public class movieDetails { 


private String movieName; 
private String description; 
private String movieLocation; 
private String movieTime; 
private int movieThreator; 

public movieDetails(String movieName, String description, String movieLocation, String movieTime, int movieThreator) { 
    this.movieName = movieName; 
    this.description = description; 
    this.movieLocation = movieLocation; 
    this.movieTime = movieTime; 
    this.movieThreator = movieThreator; 
} 

movieDetails(String string) { 
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates. 
} 

public String getMovieName() { 
    return movieName; 
} 

public String getDescription() { 
    return description; 
} 

public String getMovieLocation() { 
    return movieLocation; 
} 

public String getMovieTime() { 
    return movieTime; 
} 

public int getMovieThreator() { 
    return movieThreator; 
} 


public void setMovieName(String movieName) { 
    this.movieName=movieName; 
} 

public void setDescription(String description) { 
    this.description=description; 
} 

public void setMovieLocation(String movieLocation) { 
    this.movieLocation=movieLocation; 
} 

public void setMovieTime(String movieTime) { 
    this.movieTime=movieTime; 
} 

public void setMovieThreator(int movieThreator) { 
    this.movieThreator=movieThreator; 
} 




} 

然後在數據庫中實現類我回到這個ObservableList

public ObservableList movies_listView() throws ClassNotFoundException, SQLException{ 

    ObservableList<movieDetails> movieDetails_Table = FXCollections.observableArrayList(); 

    Class.forName(driver); 
     conn = DriverManager.getConnection(url,dbuser,dbpassw); 
     ResultSet rs = conn.createStatement().executeQuery("SELECT movie_name,description,cinema_location,time,threator FROM movie"); 

     while(rs.next()){ 
     movieDetails_Table.add(new movieDetails(

          rs.getString("movie_name"), 
          rs.getString("description"), 
          rs.getString("cinema_location"), 
          rs.getString("time"), 
          rs.getInt("threator") 


          ));         
    } 
      conn.close(); 


     return movieDetails_Table; 
} 

，並在主類

TableView<movieDetails> movieDetails_table = new TableView<>(); 

    TableColumn<movieDetails,String> movieNameCal=new TableColumn<>("Movie Name"); 
    TableColumn<movieDetails,String> movieDesCal=new TableColumn<>("Description"); 
    TableColumn<movieDetails,String> movieLocCal=new TableColumn<>("Movie Location"); 
    TableColumn<movieDetails,String> movieTimCal=new TableColumn<>("Movie Time"); 
    TableColumn<movieDetails,Integer> movieThreCal=new TableColumn<>("Movie Threator"); 


    movieNameCal.setCellValueFactory(new PropertyValueFactory<>("movie Name")); 
    movieDesCal.setCellValueFactory(new PropertyValueFactory<>("description")); 
    movieLocCal.setCellValueFactory(new PropertyValueFactory<>("movie Location")); 
    movieTimCal.setCellValueFactory(new PropertyValueFactory<>("movie Time")); 
    movieThreCal.setCellValueFactory(new PropertyValueFactory<>("movie Threator")); 


movieDetails_table.getColumns().add(movieNameCal); 
    movieDetails_table.getColumns().add(movieDesCal); 
    movieDetails_table.getColumns().add(movieLocCal); 
    movieDetails_table.getColumns().add(movieTimCal); 
    movieDetails_table.getColumns().add(movieThreCal); 


    deleteMovie_pane.setCenter(movieDetails_table); 


// this button to navigate the scene where the table in 
deleteMovie_button.setOnAction(e->{ 

     try { 



      movieDetails_table.setItems(db.movies_listView()); 
      primaryStage.setTitle("Delete Movie Scene"); 
      primaryStage.setScene(deleteMovie_scene); 
      primaryStage.show(); 
     } catch (ClassNotFoundException | SQLException ex) { 
      Logger.getLogger(Java_CinemaTicket.class.getName()).log(Level.SEVERE, null, ex); 
     } 

    }); 

當我運行IDE表示沒有錯誤，但只顯示一列填寫的信息，但其餘的沒什麼

輸出畫面

您尚未將列添加到表中。使用

movieDetails_table.getColumns().add(movieNameCal); 

等
