要實現中文排序的功能，需要重寫Ext.data.Store的applySort函數，可以把它放在ext-all.js檔案的最後，或者是放到HTML頁面的最上面，要在ExtJS初始化之後，實際代碼調用之前執行，這樣重寫的方法才能起作用，中文排序也就實現了。完整的實現代碼如下：

<script type="text/javascript" src="../ext-3.4.0/ext-all.js"></script>
<script type="text/javascript">
Ext.data.Store.prototype.applySort=function(){//重載applySort
if(this.sortInfo && !this.remoteSort){
  var s = this.sortInfo, f=s.field;
  var st=this.fields.get(f).sortType;
  var fn=function(r1,r2){
   var v1=st(r1.data[f]),v2=st(r2.data[f]);
   //添加：修複漢字排序異常的Bug
   if(typeof(v1)=="string"){//若為字串
    return v1.localeCompare(v2);//則localeCompare比較漢字字串，Firefox與IE均支援

   }//添加結束
   return v1>v2 ? 1 : (v1<v2 ? -1 : 0);
  };
  this.data.sort(s.direction,fn);
  if(this.snapshot && this.snapshot!=this.data){
   this.snapshot.sort(s.direction,fn);
  }

}
};
</script>
<script type="text/javascript">
Ext.onReady(function(){
var cum = new Ext.grid.ColumnModel([
  {header:"項目ID",dataIndex:'project_id'},
  {header:"項目名稱",dataIndex:'project_name'},
  {header:"部門",dataIndex:'project_dept_no'},
  {header:"專案經理",dataIndex:'project_manager'},
  {header:"開發經理",dataIndex:'project_leader'}
]);

var cumdata=[
  ['1','教學管理系統','001','李潤','田成功'],
  ['2','留言系統','002','光明','周愛卿'],
  ['3','圖書管理系統','008','毛小強','黃岩'],
  ['4','校信通','003','王磊','郭強']
];

var store=new Ext.data.Store({
  proxy:new Ext.data.MemoryProxy(cumdata),
  reader:new Ext.data.ArrayReader({},[
   {name:'project_id'},
   {name:'project_name'},
   {name:'project_dept_no'},
   {name:'project_manager'},
   {name:'project_leader'}
  ]),
  sortInfo:{field:'project_name',direction:'ASC'}//設定project_name欄位，按升序排列
});

store.load();

var cumgrid =new Ext.grid.GridPanel({
  renderTo:'cumGrid',
  store:store,
  height:200,
  width:500,
  colModel:cum
});
});
</script>
</head>
<body>
<div id="cumGrid"></div>
