我不能那样打印两张桌子！到目前为止，这是我的代码：
// Center
JPanel panel_center = new JPanel();
panel_overview.add(panel_center, BorderLayout.CENTER);
panel_center.setLayout(new BorderLayout());
JPanel panel_center_table = new JPanel();
panel_center.add(panel_center_table, BorderLayout.NORTH);
panel_center_table.setLayout(new GridLayout(2, 1));
JPanel panel_table_north = new JPanel();
panel_center_table.add(panel_table_north);
JPanel panel_table_south = new JPanel();
panel_center_table.add(panel_table_south);
JPanel panel_center_combobox = new JPanel();
panel_center.add(panel_center_combobox, BorderLayout.NORTH);
panel_center_combobox.setLayout(new BorderLayout());
panel_center_combobox.add(combobox_table_chooser, BorderLayout.WEST);
