前言
既然之前用到了导出，干脆凑齐它们，把Excel的导出也实现了吧，下面是我最终的实现效果图，其中主要用到了图片插入、单元格合并，单元格样式等操作
内容
好像Excel的导出没有太多重要的”知识点”，所以直接把自己的实现代码贴出来。
List<Model_LIST> Model = _modelList.GetModelListByNUM(Class_ID);
HSSFWorkbook book = new HSSFWorkbook();
IRow _row;
ICell cell;
#region [-Style-设置单元格样式]
CellStyleConfiguration style_Default = new CellStyleConfiguration(book)
.SetFontName("宋体")
.SetFontHeightInPoints(12)
.SetFontBoldweight(FontBoldWeight.NORMAL);
CellStyleConfiguration style_Border = new CellStyleConfiguration(book)
.SetFontName("宋体")
.SetFontHeightInPoints(11)
.SetFontBoldweight(FontBoldWeight.BOLD)
.SetFontColor(HSSFColor.BLACK.index)
.SetBorderBottom(NPOI.SS.UserModel.BorderStyle.THIN)
.SetBottomBorderColor(HSSFColor.BLACK.index)
.SetBorderLeft(NPOI.SS.UserModel.BorderStyle.THIN)

在导出功能的各种实现中对于这些插件的使用以及其中的特性都有了一定的了解。点滴积累，不断学习，让自己在知识的海洋里狗刨~
