jQuery CSS JavaScript UI 项目管理

项目进度管理最直观的展现就是甘特图，最近项目需求要在网页中安排任务，管理进度等，故研究了一下甘特图，在网上找到一个关于jQuery做甘特图的插件，写的非常好。

具体地址如下：http://github.com/thegrubbsian/jquery.ganttView

不过该甘特图插件没有现成编辑功能，故有找到一个改版：

http://github.com/nkmrshn/jquery.ganttView

改版后的甘特图可以编辑功能，效果图如下：

具体使用方法如下：

1. 下载文件，目录结果如下：

/example
/lib
jquery.ganttView.js
jquery.ganttView.css

2. 代码如下：
