在Swing GridLayout中动态添加新行-如何启用滚动

Question

我已经动态地向网格视图添加了行。当行数超过屏幕上显示的行数时，其余内容将被隐藏。如何启用滚动以查看未显示行的其余部分?

    JPanel billItemsPanel = new JPanel();
    GridLayout billItemsLayout = new GridLayout(0,6);
    billItemsLayout.setVgap(20);
    billItemsPanel.setLayout(billItemsLayout);
    billItemsPanel.add(new Label("Mobile Number"));
    billItemsPanel.add(new TextField(20));
    billItemsPanel.add(new Label(""));
    billItemsPanel.add(new Label(""));
    billItemsPanel.add(new Label(""));
    billItemsPanel.add(new Label(""));  
for(int i=0; i<10; i++){
    billItemsPanel.add(new TextField("Hi SKU"));
    billItemsPanel.add(new Label("Hi Title"));
    billItemsPanel.add(new Label("Hi Type"));
    billItemsPanel.add(new TextField("Hi Qty"));
    billItemsPanel.add(new Label("Hi Price"));
    billItemsPanel.add(new Label("Hi Amount"));
    billItemsPanel.add(new TextField("Bye SKU"));
    billItemsPanel.add(new Label("Bye Title"));
    billItemsPanel.add(new Label("Bye Type"));
    billItemsPanel.add(new TextField("Bye Qty"));
    billItemsPanel.add(new Label("Bye Price"));
    billItemsPanel.add(new Label("Bye Amount"));
}
