ExtJs 中一个Toolbar 不够用？再来一个！

 var grid = new Ext.grid.GridPanel({      
  id:'gridls',
  loadMask:{msg:'数据处理中...'},
  cm:new Ext.grid.ColumnModel(
  [
   csm,
   {header:"化验日期",dataIndex:"assayRecordAssayDate",sortable:true,width:100},
   {header:"生产单位",dataIndex:"innerUnitName",sortable:true,width:100,renderer:showConsigneeName}
  ]),
  sm:csm,
  store:store,
  items:[
   toolbar1
  ],
  tbar:toolbar2,
  bbar:pageBar
 });
