.NET/C#- EPPLUS DEMO

　　强大的导出EXCEL，比NPOI更好用，更强大，可惜只有4.0版本的。

　　记录一下DEMO

                var sheet = p.Workbook.Worksheets.Add("My Sheet");

                //Cells的起始索引是1
                sheet.Cells[, ].Value = 1234.123;
                sheet.Cells[, ].Value = ;
                sheet.Cells[, ].Value = ;
                sheet.Cells[, ].Value = ;

                sheet.Cells[, ].Style.Numberformat.Format = "#,##0.00";//这是保留两位小数

                var sheet2 = p.Workbook.Worksheets.Add("My Sheet2");
                sheet2.Cells[, ].Value = "jie";
                sheet2.Cells[, ].Value = "xiaom";
                sheet2.Cells[, ].Value = "ccx";
                sheet2.Cells[, ].Value = "zhangs";

                sheet2.Cells[, ].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;//水平居中
                sheet2.Cells[, ].Style.Font.Bold = true;//字体为粗体
                sheet2.Cells[, ].Style.Font.Size = ;//字体大小

                p.SaveAs(new FileInfo(@"F:\Temp\output.xlsx"));
