解决方案
如果是表头参照一下：http://liuqing-2010-07.iteye.com/blog/994858如果是其他标题需要用JLable的哟！
解决方案二：
你说的是Jtable的表头吧 而不是标题？
解决方案三：
public TableRightTest() {this.setSize(800, 500);this.setLocation(250, 150);this.setLayout(null);this.setResizable(false);this.setVisible(true);this.initTable();this.setTitle("hello");//设置标题？}
