java - fxml TableView中的错误

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>

以下称为此fxml

父级p = FXMLLoader.load（getClass（）。getResource（“ UnitTypeTable.Ffxml”））;

FXML的控制器：

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

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

    }
}

我有一个例外：

如何解决这个错误？
谢谢

最佳答案

在fxml文件中用TableColumn包裹<columns> </columns>。
