　　Execl功能非常强大，内置的很多函数或公式可以大大提高对数据的加工处理能力。那么在web中有没有类似的控件呢？经过一番搜寻，发现handsontable具备了基本的excel功能支持公式，同时能对数据进行实时编辑。另外支持拖动复制、Ctrl+C 、Ctrl+V 等等。在浏览器支持方面，它支持以下的浏览器： IE7+, FF, Chrome, Safari, Opera。

首先引入相关库文件，公式支持不包含在handsontable.full.js中，需要单独引入：

<span style="color: #008080;"> 1</span> <span style="color: #0000ff;"><span style="color: #800000;">script </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="http://handsontable.github.io/handsontable-ruleJS/lib/jquery/jquery-1.10.2.js"</span><span style="color: #0000ff;">></span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span>

在HTML中放置一个Div容器来存放handsontable控件：

<span style="color: #008080;">1</span> <span style="color: #0000ff;"><span style="color: #800000;">body</span><span style="color: #0000ff;">></span>

在javascript代码中，首先获取div容器，然后创建表格控件：
