Java fxml TableView中出现错误

我创建描述表的FXML文件

 <AnchorPane fx:id="AnchorPane" id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" fx:controller="ru.pfr03.sprut.client.UnittypeController"> 
      <children> 
        <TableView fx:id="unitTypeTableView" prefHeight="400.0" prefWidth="600.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0"> 
          <TableColumn prefWidth="100.0" text="Код"> 
          </TableColumn> 
          <TableColumn prefWidth="125.0" text="Наименование"> 
          </TableColumn> 
        </TableView> 
      </children> 
    </AnchorPane> 

如何修复此错误？

谢谢

在fxml文件中用

包装

表格列

s

public class UnittypeController implements Initializable { 
    @FXML 
    private TableView<Unittype> unitTypeTableView; 

    @Override 
    public void initialize(URL url, ResourceBundle rb) { 

    }   
}
