换行
private void NewLine(XWPFParagraph paragraph)
{
paragraph.CreateRun().AddCarriageReturn();//新增式换行--当前行之后
paragraph.CreateRun().SetText("");
//para.InsertNewRun(row).AddCarriageReturn(); //插入式换行--当前行之前
//para.InsertNewRun(row).SetText("换行001");
}
注：换行问题，不同版本的word或者npoi 版本操作方式存在不一致现象，需要亲测
private void NewLine(XWPFParagraph paragraph, string value)
{
value = value + "\r\n";
//paragraph.CreateRun().AddCarriageReturn();//新增式换行--当前行之后
paragraph.CreateRun().SetText(value);
//paragraph.CreateRun().AddCarriageReturn();
//paragraph.CreateRun().Paragraph.CreateRun().AddCarriageReturn();
//paragraph.CreateRun().Paragraph.CreateRun().SetText(value);
