C#/VB.NET 对Excel单元格填充背景色

我们知道，在处理很多表格时会遇到各种各样纷繁复杂的数据，数据较多时，如果是在没有进行数据分类的情况下，想要快速地辨别出不同类别的数据可能会花费不少时间，而且难免也会出错。在众多分类数据的方法中，对数据表格中的单元格进行颜色填充可以说是比较简单粗暴的了，同时，也可以美化表格，让人看数据时也没那么枯燥乏味。

那么，在C#语言环境中，如何来通过代码步骤实现对表哥单元格的颜色填充呢，下面的例这个操作方法给出了答案！文章转载自http://www.cnblogs.com/Yesi/p/7569580.html ，有兴趣可以自行查看详细内容。

说明：操作中使用到了组件Spire.XLS for .NET,写入代码前，需要先下载安装，并添加引用dll文件
