如果在FXML中指定了控制器，则无法将数据添加到TableView。如果未指定控制器，则无法绑定`onAction`

<TableView fx:id="tableView">
    <columns>
        <TableColumn fx:id="column1" text="Column 1" />
        <TableColumn fx:id="column2" text="Column 2" />
    </columns>
</TableView>

@FXML
private TableView<Data> tableView;
@FXML
private TableColumn<Data, String> column1;
@FXML
private TableColumn<Data, String> column2;

private ObservableList<Data> dataList = FXCollections.observableArrayList();

public void initialize() {
    tableView.setItems(dataList);
    column1.setCellValueFactory(new PropertyValueFactory<>("property1"));
    column2.setCellValueFactory(new PropertyValueFactory<>("property2"));
}

public void addData() {
    Data newData = new Data("Value 1", "Value 2");
    dataList.add(newData);
}

<Button text="Add Data" onAction="#addData" />
