用这个excel导出组件试试
- C# code
public static void ExportToTable(System.Data.DataTable dtData, string filename) { XlsDocument xls = new XlsDocument(); Worksheet sheet = xls.Workbook.Worksheets.AddNamed(filename);//状态栏标题名称 int rowNum = dtData.Rows.Count; int columnNum = dtData.Columns.Count; int rowIndex = 1; int columnIndex = 0; //生成格式列 ColumnInfo colInfo = new ColumnInfo(xls, sheet); colInfo.ColumnIndexStart = 0; colInfo.ColumnIndexEnd = Convert.ToUInt16(columnNum); colInfo.Width = 20 * 256; sheet.AddColumnInfo(colInfo); //绑定标题 Cell cell = null; foreach (DataColumn dc in dtData.Columns) { columnIndex++; cell = sheet.Cells.AddValueCell(rowIndex, columnIndex, dc.ColumnName); //cell.HorizontalAlignment = HorizontalAlignments.Centered; //cell.Font.Weight = FontWeight.Bold; //cell.PatternColor = Colors.Default30; //cell.RightLineColor = Colors.Black; //cell.RightLineStyle = 1; //cell.BottomLineColor = Colors.Black; //cell.BottomLineStyle = 1; //cell.TopLineColor = Colors.Black; //cell.TopLineStyle = 1; cell.HorizontalAlignment = HorizontalAlignments.Centered; cell.VerticalAlignment = VerticalAlignments.Centered; cell.Pattern = 1; cell.PatternColor = Colors.EgaBlue; cell.UseBorder = true; cell.TopLineStyle = 1; cell.TopLineColor = Colors.Black; cell.BottomLineStyle = 1; cell.BottomLineColor = Colors.Black; cell.LeftLineStyle = 1; cell.LeftLineColor = Colors.Black; cell.RightLineStyle = 1; cell.RightLineColor = Colors.Black; cell.Font.Bold = true; cell.Font.Height = 11 * 20; cell.Font.ColorIndex = 1; } //绑定子项数据 for (int i = 0; i < rowNum; i++) { rowIndex++; columnIndex = 0; for (int j = 0; j < columnNum; j++) { columnIndex++; cell = sheet.Cells.AddValueCell(rowIndex, columnIndex, dtData.Rows[i][j].ToString()); cell.HorizontalAlignment = HorizontalAlignments.Centered; cell.TextWrapRight = true; cell.VerticalAlignment = VerticalAlignments.Top; if (j == 0) { cell.LeftLineColor = Colors.Black; cell.LeftLineStyle = 1; } cell.RightLineColor = Colors.Black; cell.RightLineStyle = 1; cell.BottomLineColor = Colors.Black; cell.BottomLineStyle = 1; } } //导出 xls.FileName = filename; xls.Send(); }
