.net用NPOI生成Word表格

NPOI读取或生成Excel是非常容易弄懂和实现的，但是生成word表格就不容易了，特别是行列合并，以及同一个单元格内用多种样式，以下是我在项目中生成word表格时的部分代码，记下来备忘。

  1 CT_SectPr srcpr = new CT_SectPr();
  2                 //设置A4纸纵向，如果要横向，两个值调换即可
  3                 srcpr.pgSz.w = (ulong)11906;
  4                 srcpr.pgSz.h = (ulong)16838;
  5
  6                 XWPFDocument doc = new XWPFDocument();
  7                 doc.Document.body.sectPr = srcpr;
  8                 //输出标题
  9                 XWPFParagraph ptitle = doc.CreateParagraph();
 10                 ptitle.Alignment = ParagraphAlignment.CENTER;
 11                 XWPFRun titlerun = ptitle.CreateRun();
 12                 titlerun.SetText(string.Format("{0}营销考勤与工作计划",para.date));
 13                 titlerun.SetBold(true);
 14                 titlerun.FontFamily = "华文行楷";
 15                 titlerun.FontSize = 30;
 16                 titlerun.SetColor("blue");

用的dll是从github上下载的最新的，其实也不新了，2015年版的，有需要的自己去下吧
