jscrollpane有jtable设置标题出现问题。。

Jscrollpane中加入Jtable
使用如下代码设置Jtable标头：

		

String columnName[] ={"入库编号","商品名称","单价","数量","单位","总额","供应商","入库去向","入库时间","车辆","司机","押运员"};

		table = new JTable(){

			public boolean isCellEditable(int row, int column) //重写了isCellEditable方法

            { 

                       return false;//表格不允许被编辑

            }

		};

		dftm =(DefaultTableModel) table.getModel();

		dftm.setColumnIdentifiers(columnName);//设置表头

		scrollPane.setViewportView(table);

理论上应该是JTable表头显示在JSCrollPane标题的下方，但实际却显示在它上面，这是什么情况？？？？？怎么解决

To add a border around the main viewport, you can use setViewportBorder. (Of course, you can also add a border around the whole scroll pane using setBorder.)

代码没贴完，border怎么设置的 GUI需要一步一步调整才能看到效果。

		JScrollPane scrollPane = new JScrollPane();
		scrollPane.setViewportBorder(new TitledBorder(UIManager
				.getBorder("TitledBorder.border"),
				"\u5F85\u6DFB\u52A0\u9879\u76EE\uFF1A", TitledBorder.LEADING,
				TitledBorder.TOP, null, null));
		GridBagConstraints gbc_scrollPane = new GridBagConstraints();
		gbc_scrollPane.gridwidth = 4;
		gbc_scrollPane.insets = new Insets(0, 0, 5, 5);
		gbc_scrollPane.fill = GridBagConstraints.BOTH;
		gbc_scrollPane.gridx = 1;
		gbc_scrollPane.gridy = 1;
		contentPane.add(scrollPane, gbc_scrollPane);

这个是border的设置。。
