NPOI导出EXCEL 打印设置分页及打印标题

在用NPOI导出EXCEL的时候设置分页，在网上有查到用sheet1.SetRowBreak(i)方法，但一直都没有起到作用。经过研究是要设置  sheet1.FitToPage = false; 而这个属性默认是true的，怪不得一直设置都不起作用。

设置打印标题用

hssfworkbook.SetRepeatingRowsAndColumns(0, 0, 5, 0, 5);

但最新版本已经有新的方法了。

            Sheet sheet1 = hssfworkbook.CreateSheet("Sheet1");
            sheet1.SetMargin(MarginType.RightMargin, (double)0.5);
            sheet1.SetMargin(MarginType.TopMargin, (double)0.6);
            sheet1.SetMargin(MarginType.LeftMargin, (double)0.4);
            sheet1.SetMargin(MarginType.BottomMargin, (double)0.3);

            sheet1.PrintSetup.Copies = 3;
            sheet1.PrintSetup.NoColor = true;
            sheet1.PrintSetup.Landscape = true;
            sheet1.PrintSetup.PaperSize = (short)PaperSize.A4;

            sheet1.PrintSetup.FitHeight = 2;
            sheet1.PrintSetup.FitWidth = 3;
            sheet1.IsPrintGridlines = true;

            //是否填充界面
            sheet1.FitToPage = false;
            //设置打印标题
            hssfworkbook.SetRepeatingRowsAndColumns(0, 0, 5, 0, 5);
