我在表格中添加了选项table.setTableMenuButtonVisible(true);为了显示和隐藏列。
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.geometry.Insets;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;
public class MainApp extends Application
{
private TableView table = new TableView();
public static void main(String[] args)
{
launch(args);
}
@Override
public void start(Stage stage)
{
Scene scene = new Scene(new Group());
stage.setTitle("Table View Sample");
stage.setWidth(300);
stage.setHeight(500);
final Label label = new Label("Address Book");
label.setFont(new Font("Arial", 20));
table.setEditable(true);
TableColumn firstNameCol = new TableColumn("First Name");
TableColumn lastNameCol = new TableColumn("Last Name");
TableColumn emailCol = new TableColumn("Email");
table.getColumns().addAll(firstNameCol, lastNameCol, emailCol);
table.setTableMenuButtonVisible(true);
final VBox vbox = new VBox();
vbox.setSpacing(5);
vbox.setPadding(new Insets(10, 0, 0, 10));
vbox.getChildren().addAll(label, table);
((Group) scene.getRoot()).getChildren().addAll(vbox);
stage.setScene(scene);
stage.show();
}
}
我可以默认显示列First Name
和Last Name
并隐藏Email
吗?
这有什么选择吗?
