在论坛中移动JTable

Question

我试图让JTable显示在我的论坛上，但我想要一个顶行是一个带有一排按钮的“菜单”。我尝试了多种方法来实现这一点，但我无法让JTable向下移动。我评论过的部分是我一直在玩的东西。

Table1 = new JTable(data, columnNames);
        Table1.setPreferredScrollableViewportSize(new Dimension(1000, 600));
        Table1.setFillsViewportHeight(true);
    JScrollPane scrollPane = new JScrollPane(Table1);   
        add(scrollPane);
        scrollPane.setLocation(0,300);
    Container TopMenu = getContentPane();
    SpringLayout TopMenuLayout = new SpringLayout();
        TopMenuLayout.putConstraint(SpringLayout.WEST, project1, 325, SpringLayout.WEST, TopMenu);
        TopMenuLayout.putConstraint(SpringLayout.NORTH, project1, 5, SpringLayout.NORTH, TopMenu);
        TopMenuLayout.putConstraint(SpringLayout.WEST, project2, 100, SpringLayout.WEST, project1);
        TopMenuLayout.putConstraint(SpringLayout.NORTH, project2, 5, SpringLayout.NORTH, TopMenu);
        TopMenuLayout.putConstraint(SpringLayout.WEST, project3, 100, SpringLayout.WEST, project2);
        TopMenuLayout.putConstraint(SpringLayout.NORTH, project3, 5, SpringLayout.NORTH, TopMenu);
        TopMenuLayout.putConstraint(SpringLayout.WEST, project4, 100, SpringLayout.WEST, project3);
        TopMenuLayout.putConstraint(SpringLayout.NORTH, project4, 5, SpringLayout.NORTH, TopMenu);
        TopMenuLayout.putConstraint(SpringLayout.WEST, project5, 100, SpringLayout.WEST, project4);
        TopMenuLayout.putConstraint(SpringLayout.NORTH, project5, 5, SpringLayout.NORTH, TopMenu);
        //TopMenuLayout.putConstraint(SpringLayout.NORTH, Table1, 150, SpringLayout.NORTH, this);
    TopMenu.setLayout(TopMenuLayout);
        //TopMenu.add(scrollPane);
        TopMenu.add(project1);
        //TopMenu.add(Table1);
        TopMenu.add(project2);
        TopMenu.add(project3);
        TopMenu.add(project4);
        TopMenu.add(project5);
