OpenXML を介して Excel の行にセルを追加する必要があります。ただし、以下のコードはうまく機能していないようです。これを機能させるための助けをいただければ幸いです。

private Row PadRow(Row row, int p)
{
    try
    {
        int currentcount = p - row.Descendants<Cell>().Count<Cell>();
        for (int count = 0; count < currentcount; count++)
            row.Append(new Cell() { DataType = CellValues.String, CellValue = new CellValue(" ") });
    }
    catch (Exception ex)
    {
        throw ex;
    };
    return row;
}

                    }
