前言
前面介绍了NPOI单元格样式的使用、单元格合并，以及NPOI提供的颜色。现在用上前面的一些知识点，做一个测试结果表格。
1、 介绍NPOI 的颜色卡、名称以及索引 https://editor.csdn.net/md/?articleId=130265415
2、 NPOI的CellStyle单元格样式 https://editor.csdn.net/md/?articleId=130245869
3、 将DataTable中的数据保存到Excel （二） 使用NPOI https://editor.csdn.net/md/?articleId=130225379
初版表格，单元格的合并
先上一个简单版本的，主要内容在于跨行和跨列单元格的合并。涉及的主要函数是Sheet的AddMergedRegion 以及NPOI.SS.Util.CellRangeAddress这两个函数。
这里使用的NPOI版本是 2.0.6.0， 框架 .NET Framework 4.0。
using NPOI.HSSF.Util;
using NPOI.HSSF.UserModel;
using NPOI.SS.UserModel;

{
//创建工作簿对象
HSSFWorkbook workBook = new HSSFWorkbook();
//创建一个sheet
ISheet sheet = workBook.CreateSheet("MergeTable");
IRow row;
ICell cell;
//行索引
int rowIndex = 0;
//标题
row = sheet.CreateRow(rowIndex);
cell = row.CreateCell(0);
cell.SetCellValue("测试报告");

效果图：
进阶表格，单元格美化
设置行高列宽，对单元格的对齐方式、边框、字体大小IFont、颜色进行设置美化, 使用的是ICellStyle.
先看一下最终的效果图，由结果分析向上分析。
测试报告
行高30，居中显示，字体： 黑体，16号，加粗， 设置单元格边框。
//大标题 黑体 16号 加边框 居中显示 行高30
string fontName = "黑体";
ICellStyle totalHeader = workBook.CreateCellStyle();
//垂直居中对齐
totalHeader.Alignment = NPOI.SS.UserModel.HorizontalAlignment.Center;
totalHeader.VerticalAlignment = VerticalAlignment.Center;
//边框
totalHeader.BorderTop = NPOI.SS.UserModel.BorderStyle.Thin;
totalHeader.BorderBottom = NPOI.SS.UserModel.BorderStyle.Thin;
totalHeader.BorderLeft = NPOI.SS.UserModel.BorderStyle.Thin;
totalHeader.BorderRight = NPOI.SS.UserModel.BorderStyle.Thin;
//字体
IFont totalFont = workBook.CreateFont();
totalFont.FontName = fontName;
totalFont.FontHeightInPoints = 16;
totalFont.Boldweight = (short)NPOI.SS.UserModel.FontBoldWeight.Bold;
totalHeader.SetFont(totalFont);
第二行 机型
行高20， 居中显示， 字体 ：微软雅黑12号 设置单元格边框。
//中间行样式 机型 行高20 居中显示 字体 微软雅黑12号 加边框
ICellStyle lineStyle = workBook.CreateCellStyle();
//垂直居中对齐
lineStyle.Alignment = NPOI.SS.UserModel.HorizontalAlignment.Center;
lineStyle.VerticalAlignment = VerticalAlignment.Center;
//边框
lineStyle.BorderTop = NPOI.SS.UserModel.BorderStyle.Thin;
lineStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.Thin;
lineStyle.BorderLeft = NPOI.SS.UserModel.BorderStyle.Thin;
lineStyle.BorderRight = NPOI.SS.UserModel.BorderStyle.Thin;
//字体大小
IFont midFont = workBook.CreateFont();
midFont.FontHeightInPoints = 12;
midFont.FontName = "微软雅黑";
lineStyle.SetFont(midFont);
左侧跨单元格 品质（性能）测试 总结果
居中显示， 字体微软雅黑12号加粗 ，设置单元格边框。在单元格合并后再设置样式。
//左侧跨行单元格的样式 居中显示 字体微软雅黑12号加粗 设置单元格边框
ICellStyle leftCellStyle = workBook.CreateCellStyle();
//对齐
leftCellStyle.Alignment = NPOI.SS.UserModel.HorizontalAlignment.Center;
leftCellStyle.VerticalAlignment = VerticalAlignment.Center;
//边框
leftCellStyle.BorderTop = NPOI.SS.UserModel.BorderStyle.Thin;
leftCellStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.Thin;
leftCellStyle.BorderLeft = NPOI.SS.UserModel.BorderStyle.Thin;
leftCellStyle.BorderRight = NPOI.SS.UserModel.BorderStyle.Thin;
//字体大小
IFont leftFont = workBook.CreateFont();
leftFont.FontHeightInPoints = 12;
leftFont.FontName = "微软雅黑";
leftFont.Boldweight = (short)(short)NPOI.SS.UserModel.FontBoldWeight.Bold; ;
leftCellStyle.SetFont(leftFont);
带背景小标题
行高20，居中显示，字体字体微软雅黑12号，设置单元格边框，设置背景色。
要想设置的背景色起作用，必须要设置 midTitleStyle.FillPattern = FillPattern.SolidForeground;这句
//小标题的样式 行高20，居中显示，字体字体微软雅黑12号，设置单元格边框，设置背景色
ICellStyle midTitleStyle = workBook.CreateCellStyle();
//对齐
midTitleStyle.Alignment = NPOI.SS.UserModel.HorizontalAlignment.Center;
midTitleStyle.VerticalAlignment = VerticalAlignment.Center;
//边框
midTitleStyle.BorderTop = NPOI.SS.UserModel.BorderStyle.Thin;
midTitleStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.Thin;
midTitleStyle.BorderLeft = NPOI.SS.UserModel.BorderStyle.Thin;
midTitleStyle.BorderRight = NPOI.SS.UserModel.BorderStyle.Thin;
//需要设置图例，颜色才会起作用
midTitleStyle.FillPattern = FillPattern.SolidForeground;
//背景颜色
midTitleStyle.FillForegroundColor = HSSFColor.Grey25Percent.Index;
midTitleStyle.SetFont(midFont);
中间的测试内容
行高15，左对齐，设置单元格边框。
//内容的样式 行高15 左对齐 设置单元格边框
ICellStyle contentStyle = workBook.CreateCellStyle();
//对齐
contentStyle.Alignment = NPOI.SS.UserModel.HorizontalAlignment.Left;
contentStyle.VerticalAlignment = VerticalAlignment.Center;
//边框
contentStyle.BorderTop = NPOI.SS.UserModel.BorderStyle.Thin;
contentStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.Thin;
contentStyle.BorderLeft = NPOI.SS.UserModel.BorderStyle.Thin;
contentStyle.BorderRight = NPOI.SS.UserModel.BorderStyle.Thin;
