java - JavaFX TableColumn ソートの問題

Question

私のプログラムは、3 列のテーブルを表示します。列のヘッダーをクリックすると、TableView の内容がソートされません。

このチュートリアル(列内のデータの並べ替えを参照) を正しく理解していれば、テーブルの並べ替えメカニズムを使用できるようにするために特別な実装を行う必要はありません。

FXML:

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

<AnchorPane id="AnchorPane" prefHeight="400.0" prefWidth="600.0" xmlns:fx="http://javafx.com/fxml" fx:controller="br.meuspila.javafx.ListarCorretorasController">
  <children>
    <TableView fx:id="tabelaCorretoras" prefHeight="400.0" prefWidth="600.0">
      <columns>
        <TableColumn prefWidth="150.0" text="Nome" fx:id="colunaNome" />
        <TableColumn prefWidth="75.0" text="Código" fx:id="colunaCodigo" />
        <TableColumn prefWidth="200.0" text="Descrição" fx:id="colunaDescricao" />
      </columns>
    </TableView>
  </children>
</AnchorPane>
