如何使用ASP从数据库导出数据到excel表。净MVC吗?

Does anyone know any simple NuGet package or other way to export data from database to Excel? I have a few tables and each one I'd like to export to other WorkSheet, but in same Excel file.

有谁知道任何简单的NuGet包或从数据库导出数据到Excel的其他方法?我有几个表，每个表我都想导出到其他工作表中，但都在同一个Excel文件中。

Also later I'd like to import data from file Excel to database. For both operations may be different library.

稍后我还想将数据从文件Excel导入数据库。对于这两个操作，可能是不同的库。

I tried already this But it doesn't work.

我已经试过了，但是没用。

                ExcelWorksheet ws = packge.Workbook.Worksheets.Add("Demo");

                //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
                ws.Cells["A1"].LoadFromDataTable(table, true);

                //Format the header for column 1-3
                using (ExcelRange range = ws.Cells["A1:C1"])
                {
                    range.Style.Font.Bold = true;
                    range.Style.Fill.PatternType = ExcelFillStyle.Solid;                      //Set Pattern for the background to Solid
                    range.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(79, 129, 189)); //Set color to dark blue
                    range.Style.Font.Color.SetColor(Color.White);
                }

               //Example how to Format Column 1 as numeric 
                using (ExcelRange col = ws.Cells[2, 1, 2 + table.Rows.Count, 1])
                {
                    col.Style.Numberformat.Format = "#,##0.00";
                    col.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;
                }

                //Write it back to the client
                Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                Response.AddHeader("content-disposition", "attachment;  filename=ExcelExport.xlsx");
                Response.BinaryWrite(packge.GetAsByteArray());
            }
        }
