c# - 设置 Excel 电子表格列属性问题

Question

我正在尝试使用 OpenXML 框架在 Excel 电子表格中设置默认列宽，结果文件损坏。这是代码

private void initSpreadsheetDocument()
{
    // Add a WorkbookPart to the spreadsheet document.
    WorkbookPart workbookpart = spreadsheetDocument.AddWorkbookPart();
    workbookpart.Workbook = new Workbook();

    var sheetData = new SheetData();
    var properties = new SheetFormatProperties { DefaultColumnWidth = 25D };

    Worksheet worksheet = new Worksheet();
    worksheet.AppendChild(sheetData);
    
    // here is line of code that corrupt file
    // without it - file is being generated properly
    worksheet.AppendChild(properties);

    // Add a WorksheetPart to the WorkbookPart.
    WorksheetPart worksheetPart = workbookpart.AddNewPart<WorksheetPart>();
    worksheetPart.Worksheet = worksheet;

    // Init sheets
    sheetsStorage = new Sheets();

    defaultSheet = new Sheet();
    defaultSheet.Id = spreadsheetDocument.WorkbookPart.GetIdOfPart(worksheetPart);
    defaultSheet.SheetId = 1;
    defaultSheet.Name = DEFAULT_SHEET_NAME;

    sheetsStorage.AppendChild(defaultSheet);

    spreadsheetDocument.WorkbookPart.Workbook.AppendChild(sheetsStorage);
    spreadsheetDocument.WorkbookPart.Workbook.Save();
}

我试图使用“Append”与“AppendChild”，但结果是一样的

有没有人有意见如何解决？

好的。原因是 SheetFormatProperties 对象具有必需的属性 defaultRowHeight。您甚至可以指定 defaultRowHeight = 0，但它必须存在。所以使用

SheetFormatProperties sheetFormatProperties1 = new SheetFormatProperties(){ DefaultColumnWidth = 12.75D, DefaultRowHeight = 0D};
