GridView的標題欄、列凍結效果(跨瀏覽器版)
不甘心事情只做一半，又挖了一下，驚喜地發現另一個版本: Super Tables，可以支援Firefox 2+, Internet Explorer 5.5+, Safari 3+, Opera 9+ 以及Chrome，而且也支援直欄的凍結效果，在功能上大勝ScrollableTable，二話不說，通通包起來。SuperTable的原理與ScrollableTable不同，它需要額外的CSS以及在Table外包一層<div>，可視範圍大小由<div> Style決定，設定時參數也較多(如:fixedCols, headerRows...)，所以我寫了一個jQuery Plugin(jquery.superTable.js)把它包起來。有了Plugin的加持，只要一個toSuperTable(options)就可立即升級成有凍結效果的GridView了。
