Epplus - 无法更改单元格值或单元格标题

Question

更改单元格的值时遇到问题。这是我的代码:

FileInfo newFile = new FileInfo(file); ExcelPackage pck = new ExcelPackage(newFile);

        var wsData = pck.Workbook.Worksheets.Add("Absent Employee List");
        var dataRange = wsData.Cells["A1"].LoadFromCollection(
                from s in emps
                orderby s.EmployeeCode
                select s,
                true, OfficeOpenXml.Table.TableStyles.Medium2
                );
        wsData.Cells[2, 4, dataRange.End.Row, 4].Style.Numberformat.Format = "dd-mm-yyyy"
        wsData.Cells[2, 5, dataRange.End.Row, 5].Style.Numberformat.Format = "dd-mm-yyyy";

        wsData.Cells["A1"].Value = "Employee Code"; // [1, 1]
        wsData.Cells["B1"].Value = "Full Name"; // [1, 2]
        wsData.Cells["C1"].Value = "Department"; // [1, 3]

        dataRange.AutoFitColumns();

        pck.SaveAs(newFile);

创建后打开文件时，A1、B1、C1 的 header 没有改变。我错过了什么？感谢您的帮助。

试试这个

wsData.Cells[1,1].Value = "Employee Code";
wsData.Cells[2,1].Value = "Full Name";
wsData.Cells[3,1].Value = "Department"; 

这对我有用!
