Jquery 表格合并的问题分享
人气:0
这里我使用Jquery库，这个就不用过多介绍了，有几个知识点：
- 选择器tr:eq(index)，表示选择指定index索引的tr元素，index索引从0开始
- tempRow.parent()，表示返回tempRow对象的父节点对象
- $("<td/>").prependTo()，表示将一个td元素添加到指定元素的内容头部
实例代码

注释掉Jquery代码的效果图
运行Jquery代码的效果图
小结
代码写得很粗糙，只是简单做个笔记，最近在忙着整理编写一些Jquery插件和discuz插件，Python和PyQt的相关文章都未来得及整理发布，唉，时间不够用啊，只能慢慢来了。Jquery是相当不错的说，内置Sizzle选择器后，那速度更是飞一般，貌似现在到1.6版本了，希望越做越好吧！
