c# - 以编程方式在 OpenXML 中的 Excel 中填充一行

Question

我需要通过 OpenXML 在 excel 行中添加一些额外的单元格。但是，下面的代码似乎并没有起到作用。希望有任何帮助以使这项工作正常进行。

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;
}
