错误：在TableView列列表中检测到重复的TableColumns

标签： java javafx

我正在设置此函数的tablecolumns值，即。，setTable（按下一个按钮时调用）

  

实际上有两个表，但是这个表只为第一个表设置tablecolumns的值

public class abc {   
   public void setTable(ActionEvent event)throws IOException{
        //i am getting table controller because tableview is in another scene.
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("table_scene.fxml"));
        fxmlLoader.load();
        table_scene controller = fxmlLoader.getController();
        controller.C1.setCellValueFactory(new PropertyValueFactory<>("Classs"));
        controller.N1.setCellValueFactory(new PropertyValueFactory<>("Name"));
        controller.S1.setCellValueFactory(new PropertyValueFactory<>("Sec"));
        controller.table1.getColumns().addAll(controller.C1,controller.N1,controller.S1);
        controller.table1.setItems(getDetails());

public ObservableList<TableItems> getDetails() {
  ObservableList<TableItems> list = FXCollections.observableArrayList();

        //Here are jdbc codes for retreiving the value of n1,c1,v1 and so on.
        //Tell me if i should add this code

        list.add(new TableItems(n1,c1,se1));
        list.add(new TableItems(n2,c2,se2));
        list.add(new TableItems(n3,c3,se3));
        list.add(new TableItems(n4,c4,se4));
       return list;
    }
}

这是表格所在的table_scene.fxml的控制器。

public class table_scene {
    @FXML
    TableView<TableItems> table1;
    @FXML
    TableView<TableItems> table2;
    @FXML
    TableColumn<TableItems,String> N1;
    @FXML
    TableColumn<TableItems,Integer> C1;
    @FXML
    TableColumn<TableItems,String> S1;
    @FXML
    TableColumn<TableItems,String> N2;
    @FXML
    TableColumn<TableItems,Integer> C2;
    @FXML
    TableColumn<TableItems,String> V2;
}

这是从另一个场景调用的另一个函数，我在另一个tableview的表列中设置值。 有两个表。此函数将值设置为另一个表的tablecolumn。

   public class abc2 {   
   public void setTable(ActionEvent event)throws IOException{
        //i am getting table controller because tableview is in another scene.
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("table_scene.fxml"));
        fxmlLoader.load();
        table_scene controller = fxmlLoader.getController();
        controller.C2.setCellValueFactory(new PropertyValueFactory<>("Classs"));
        controller.N2.setCellValueFactory(new PropertyValueFactory<>("Name"));
        controller.S2.setCellValueFactory(new PropertyValueFactory<>("Sec"));
        controller.table2.getColumns().addAll(controller.C2,controller.N2,controller.S2);
        controller.table2.setItems(getDetails());

  public ObservableList<TableItems> getDetails() {
     ObservableList<TableItems> list = FXCollections.observableArrayList();

       //Here are jdbc codes for retreiving the value of n1,c1,v1 and so on.
        //Tell me if i should add this code

        list.add(new TableItems(n1,c1,se1));
        list.add(new TableItems(n2,c2,se2));
        list.add(new TableItems(n3,c3,se3));
        list.add(new TableItems(n4,c4,se4));
       return list;
}

}

这是吸气剂和制定者的类别。

public class TableItems {
    private String Name;
    private int Classs;
    private String Sec;

   public TableItems(String Name, int Class, String Sec){
      this.Name=Name;
      this.Classs=Class;
      this.Sec=Sec;

}


public int getClasss() {
    return Classs;
}

public void setClasss(int classs) {
    Classs = classs;
}

public String getName() {
    return Name;
}
public void setName(String name) {
    Name = name;

}

public String getSec() {
    return Sec;
}

public void setSec(String sec) {
    Sec = sec;
}

}

这是我得到的错误..
