Javafx tableview 复选框隐藏不需要的行？

Question

我正在尝试通过使用复选框从表视图（我在 scenebuilder 中制作）中隐藏一些行来做一些报告。如果 tableview 中的对象在列中没有特定的字符串，它就会变得不可见。示例：通过单击复选框，隐藏 table_adress 中所有不具有确切值“Barcelona”的行。我试着这样做，但我一直让自己复杂化。有什么想法吗？

函数

@FXML
     void CakeRequestsFromBarcelona(ActionEvent event) throws IOException {
        for(Object cake:table.getItems()) {
            for (TableColumn column : table.getColumns()) {
                //not sure how to write it
            }
        }
    }

初始化

    @FXML
    private TableColumn<CakeRequest, Integer> table_ID;
    @FXML
    private TableColumn<CakeRequest, String> table_adress;
    @FXML
    private TableColumn<CakeRequest, String> table_design;
    @FXML
    private TableColumn<CakeRequest, String> table_flavour;
    @FXML
    private TableColumn<CakeRequest, String> table_model;
    @FXML
    private TableColumn<CakeRequest, String> table_name;
    @FXML
    private TableColumn<CakeRequest, String> table_phonenumber;
    @FXML
    private TableView<CakeRequest> table;

public void initialize(){
        //cakeRequest
        table_ID.setCellValueFactory(
                p-> new SimpleIntegerProperty(p.getValue().getID()).asObject()
        );
        table_name.setCellValueFactory(
                p -> new SimpleStringProperty(p.getValue().getOwnerName())
        );
        table_adress.setCellValueFactory(
                p -> new SimpleStringProperty(p.getValue().getOwnerAddress())
        );
        table_phonenumber.setCellValueFactory(
                p -> new SimpleStringProperty(p.getValue().getPhoneNumber())
        );
        table_flavour.setCellValueFactory(
                p -> new SimpleStringProperty(p.getValue().getFlavour())
        );
        table_design.setCellValueFactory(
                p -> new SimpleStringProperty(p.getValue().getDesign())
        );
        table_model.setCellValueFactory(
                p -> new SimpleStringProperty(p.getValue().getModel())
        );
}

CakeRequest

public class CakeRequest implements Identifiable<Integer>, Serializable{
    private int ID;
    private String OwnerName;
    private String OwnerAddress;
    private String PhoneNumber;
    private String Model;
    private String Flavour;
    private String Design;

使用 FilteredList 并在复选框为 checked/unchecked 时更改谓词：

private ObservableList<CakeRequest> data = FXCollections.observableArrayList();
private FilteredList<CakeRequest> filteredData = new FilteredList<>(data, request -> true);

public void initialize(){
    // existing code...
    table.setItems(filteredData);
}

@FXML
void cakeRequestsFromBarcelona(ActionEvent event)  {
    if (checkBox.isChecked()) {
        filteredData.setPredicate(request -> request.getOwnerAddress().contains("Barcelona"));
    } else {
        filteredData.setPredicate(request -> true);
    }
}
