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

操作前：

操作后：

C#

using System.Drawing;
using Spire.Xls;namespace background_color
{class Program{static void Main(string[] args){Workbook workbook = new Workbook();workbook.LoadFromFile(@"C:\Users\Administrator\Desktop\test.xlsx", ExcelVersion.Version97to2003);Worksheet worksheet = workbook.Worksheets[0];//set the backgroundcolor of Range["A1:C2"]worksheet.Range["A1:C2"].Style.Color = Color.LightSeaGreen;//set the backgroundcolor of Range["A3:C4"]worksheet.Range["A3:C4"].Style.Color = Color.LightYellow;//set the backgroundcolor of Range["A5:C19"]worksheet.Range["A5:C19"].Style.Color = Color.SpringGreen;//set the backgroundcolor of Range["A20:C21"]worksheet.Range["A20:C21"].Style.Color = Color.DeepSkyBlue;//set the backgroundcolor of Range["A22:C23"]worksheet.Range["A22:C23"].Style.Color = Color.Yellow;//save and launch the projectworkbook.SaveToFile("Sample.xls", ExcelVersion.Version97to2003);System.Diagnostics.Process.Start(workbook.FileName);}}
}

VB.NET

Imports System.Drawing
Imports Spire.XlsNamespace background_colorClass ProgramPrivate Shared Sub Main(ByVal args() As String)Dim workbook As Workbook = New Workbookworkbook.LoadFromFile("C:\Users\Administrator\Desktop\test.xlsx", ExcelVersion.Version97to2003)Dim worksheet As Worksheet = workbook.Worksheets(0)'set the backgroundcolor of Range["A1:C2"]worksheet.Range("A1:C2").Style.Color = Color.LightSeaGreen'set the backgroundcolor of Range["A3:C4"]worksheet.Range("A3:C4").Style.Color = Color.LightYellow'set the backgroundcolor of Range["A5:C19"]worksheet.Range("A5:C19").Style.Color = Color.SpringGreen'set the backgroundcolor of Range["A20:C21"]worksheet.Range("A20:C21").Style.Color = Color.DeepSkyBlue'set the backgroundcolor of Range["A22:C23"]worksheet.Range("A22:C23").Style.Color = Color.Yellow'save and launch the projectworkbook.SaveToFile("Sample.xls", ExcelVersion.Version97to2003)System.Diagnostics.Process.Start(workbook.FileName)End SubEnd Class
