 var tabpanel_order_list=new Ext.TabPanel({

      //   renderTo:'tabpanel',
        region:'center',
        '100%',

                // html:"列表",
                id : 'tab_list',
                items:[panel_order_list]
            }
        ]
    });
   
     viewport_order_list = new Ext.Viewport({
            enableTabScroll : true,
            layout:'border',
            items:[ tabpanel_order_list]
         });
  }
  //--------------------------------------------------------------设置第二个TabPanel----修改tab的表单
  function loadTab_update_list(){
