【优点】
1、对开发人员指定的表格没有任何影响;
2、使用简单;
3、被定义的表格样式可以随意的定制你的样式,不对你的样式构成影响;
4、移植性好,扩展性好。
【缺点】
目前用IE7测试正常,但不支持FireFox,工作比较忙,没时间更正,希望网友更正,俺在此谢过。^_^
【使用方法】
1、将AutoTableSize.js包文件[点击这儿下载源代码]导入到你的web应用目录中;
2、引入包AutoTableSize.js,页面body底部加入:
<script type="text/Javascript" src="AutoTableSize.js"></script>
3、编写你的脚本调用:
new AutoTableSize(); 当DOM对象中只有一个Table的时候不用指定Table的ID属性;
new AutoTableSize(table); table:既可以是表格的ID属性,也可以是表格对象;
