Question

我正在尝试将数据添加到使用场景构建器创建的tableview中当我尝试运行程序时，tableview中只显示一列我能错过什么我已经查看了可用的示例，我看不出哪里出错了。这是我的Fxml文件

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane prefHeight="352.0" prefWidth="423.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="application.TableController">
   <children>
      <TableView fx:id="tableview" layoutX="16.0" layoutY="48.0" prefHeight="200.0" prefWidth="392.0">
        <columns>
          <TableColumn fx:id="firstcol" prefWidth="108.0" text="first" />
          <TableColumn fx:id="lastcol" prefWidth="157.0" text="lastame" />
           <TableColumn fx:id="phonecol" prefWidth="130.0" text="phone" />
        </columns>
      </TableView>
   </children>
</AnchorPane>

import javafx.fxml.FXML;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;


public class TableController {
    @FXML private   TableView <Person>tableview;
    @FXML private TableColumn<Person,String> firstcol;
    @FXML private  TableColumn <Person,String>lastcol;
    @FXML private  TableColumn <Person,String>phonecol;

    private final ObservableList<Person> data =
            FXCollections.observableArrayList(
                    new Person("Bob", "Smith","77777"),
                    new Person("Bob", "Smith","999"),
                    new Person("george", "Smith","263737")

            );
    @FXML
    protected void initialize() {

        //setting up the columns
        firstcol.setCellValueFactory( new PropertyValueFactory<Person, String>("first"));
        lastcol.setCellValueFactory( new PropertyValueFactory<Person, String>("last") );
        phonecol.setCellValueFactory( new PropertyValueFactory<Person, String>("phone") );

        //setting up the table data source

        tableview.setItems( data );
    }

}

        this.phone = new SimpleStringProperty( phone );
    }


    public String getFirstName() {
        return first.get();
    }

    public void setFirstName(String first) {
        this.first.set( first );
    }



    public String getLastName() {
        return last.get();
    }

    public void setLastName(String last) {
        this.last.set( last );
    }



    public String getPhone() {
        return phone.get();
