excel导出是用 org.in2bits.MyXls 做的，有没有人用过呀？
导出来的时间列 不是正常的格式，而是 ”41092“ 这个在哪里设置格式呀？

- C# code
public void Save(string sFilePath) { XlsDocument xls = new XlsDocument(); xls.FileName = sFilePath; int colIndex = 0; int rowIndex = 1; Worksheet sheet = xls.Workbook.Worksheets.Add("Sheet1"); Cells cells = sheet.Cells; // 表头 for (int i = 0; i < _fields.Length; i++) { if (_dataSource.Columns.Contains(_fields[i])) { colIndex++; Cell cellHeader = cells.Add(rowIndex, colIndex, _titles[i]); cellHeader.Font.Bold = true; cellHeader.Font.ColorIndex = 4; cellHeader.HorizontalAlignment = HorizontalAlignments.Left; cellHeader.UseBorder = true; cellHeader.BottomLineColor = Colors.Black; cellHeader.BottomLineStyle = 2; cellHeader.RightLineColor = Colors.Black; cellHeader.RightLineStyle = 1; } } XF dateStyle = xls.NewXF(); dateStyle.Format = "yyyy-MM-dd"; foreach (DataRow row in _dataSource.Rows) { rowIndex++; colIndex = 0; foreach (string s in _fields) { if (_dataSource.Columns.Contains(s)) { colIndex++; string cellValue = row[s].ToString(); cells.Add(rowIndex, colIndex, row[s]); if (DateTime.TryParse(cellValue, out dtValue)) { cells.Add(rowIndex, colIndex, dtValue, dateStyle); } else { cells.Add(rowIndex, colIndex, row[s]); } } } } xls.Save(true); }
