自己寫了段小代碼，希望可以供大家學習和參考。代碼里沒有太多注釋，有時間的話我會補充上去。

自己在寫動態生成DataTable的時候也查閱了很多相關文章，以及實現固定表頭等等。

在解決固定表頭問題上我是用的兩張表（加行標是3張表）實現的，因為我發現如果用JSF1.1的化實現固定表頭幾乎不可能（如果有人有好的想法，比如用JS比較在行的朋友請告訴我解決方法，謝謝）

實現給每個Header加上一個CommandLink的時候我遇到了很大的問題，就是無論如何我動態生成的這些CommandLink都沒有辦法觸發事件（并不報錯），這個問題足足折磨了我3天。。。

最后終于發現問題的所在，是因為我在生成CommandLink的時候沒有給每個CommandLink SetID。。。就加上這句話，問題立馬解決。

我原來的代碼是鏈接數據庫的，但是這樣的化大家也沒有辦法參考，所以我對代碼少繳修改，就算是個小例子吧，可重用。

希望大家對我的代碼提出寶貴意見，一起進步，謝謝。
