在Excel中打开OpenXML文件时需要修复

我正在开发一个函数,它可以将数据表转换为 .xlsx 使用OpenXML的文件。我能创造出 .xlsx文件

修复的记录:来自/xl/worksheets/sheet1.xml部分的单元格信息

我试着从类似的问题中找到解决办法,但没有任何效果。

public MemoryStream ConvertToXLSX(DataTable table, string sheetName)
{
    MemoryStream excelStream = new MemoryStream();

    using (var workbook = SpreadsheetDocument.Create(excelStream, DocumentFormat.OpenXml.SpreadsheetDocumentType.Workbook))
    {
        var workBookPart = workbook.AddWorkbookPart();
        workbook.WorkbookPart.Workbook = new DocumentFormat.OpenXml.Spreadsheet.Workbook();
        workbook.WorkbookPart.Workbook.Sheets = new DocumentFormat.OpenXml.Spreadsheet.Sheets();

        uint sheetID = 1;

        var sheetPart = workbook.WorkbookPart.AddNewPart<WorksheetPart>();
        var sheetData = new SheetData();
        sheetPart.Worksheet = new DocumentFormat.OpenXml.Spreadsheet.Worksheet(sheetData);

        DocumentFormat.OpenXml.Spreadsheet.Sheets sheets = workbook.WorkbookPart.Workbook.GetFirstChild<DocumentFormat.OpenXml.Spreadsheet.Sheets>();
        string relationshipId = workbook.WorkbookPart.GetIdOfPart(sheetPart);

        if (sheets.Elements<Sheet>().Count() > 0)
        {
            sheetID = sheets.Elements<Sheet>().Select(s => s.SheetId.Value).Max() + 1;
        }

        Sheet sheet = new Sheet() { Id = relationshipId, SheetId = sheetID, Name = sheetName };
        sheets.Append(sheet);

        Row headerRow = new Row();

        List<string> columns = new List<string>();

        foreach (DataColumn column in table.Columns)
        {
            columns.Add(column.ColumnName);
            Cell cell = new Cell();
            cell.DataType = CellValues.SharedString;
            cell.CellValue = new CellValue(column.ColumnName);
            headerRow.AppendChild(cell);
        }

        sheetData.AppendChild(headerRow);

        foreach (DataRow tabRow in table.Rows)
        {
            Row newRow = new Row();

            foreach (String col in columns)
            {
                var val = tabRow[col];

                Cell cell = new Cell();
                cell.DataType = GetCellValueType(val.GetType());
                cell.CellValue = new CellValue(val.ToString());
                newRow.AppendChild(cell);
            }

            sheetData.AppendChild(newRow);
        }

        workbook.WorkbookPart.Workbook.Save();
    }

    return excelStream;
}

以下是数据在Excel中打开后的示例:
