GridView的标题栏、列冻结效果(跨浏览器版)
本文来源：http://blog.darkthread.net/blogs/darkthreadtw/archive/2009/02/18/supertable-plugin-for-jquery.aspx
稍早发表了GridView 的标题列冻结效果，足以满足工作上的需求，不过存在两个缺点:只支援FF及IE6/7、只能冻结列不能冻结栏(行)...
不甘心事情只做一半，又挖了一下，惊喜地发现另一个版本: Super Tables，可以支援 Firefox 2+, Internet Explorer 5.5+, Safari 3+, Opera 9+以及Chrome，而且也支援直栏的冻结效果，在功能上大胜ScrollableTable，二话不说，通通包起来。
SuperTable的原理与ScrollableTable不同，它需要额外的CSS以及在Table外包一层<div>，可视范围 大小由<div> Style决定，设定时参数也较多(如:fixedCols, headerRows...)，所以我写了一个jQuery Plugin(jquery.superTable.js)把它包起来。有了Plugin的加持，只要一个toSuperTable(options)就 可立即升级成有冻结效果的GridView了。

margin: "10px", padding: "0px",
overflow: "hidden", colWidths: undefined,fixedCols: 0, headerRows: 1,
onStart: function() { },onFinish: function() { },cssSkin: "sSky"}, options);
return this.each(function() {
var q = $(this);
var id = q.attr("id");
q.removeAttr("style").wrap("<div id='" + id + "_box'></div>");
var nonCssProps = ["fixedCols", "headerRows", "onStart", "onFinish", "cssSkin", "colWidths"];
var container = $("#" + id + "_box");
for (var p in setting) {
if ($.inArray(p, nonCssProps) == -1) {container.css(p, setting[p]);
delete setting[p];
}
}
var mySt = new superTable(id, setting);
});
}
});
})(jQuery);
