Issue Description

Net8 / net6 下

            SXSSFWorkbook wb = new SXSSFWorkbook(); // keep 100 rows in memory, exceeding rows will be flushed to disk
            ISheet sh = wb.CreateSheet();
            for (int rownum = 0; rownum < 1000; rownum++)
            {
                IRow row = sh.CreateRow(rownum);
                for (int cellnum = 0; cellnum < 10; cellnum++)
                {
                    ICell cell = row.CreateCell(cellnum);
                    String address = new CellReference(cell).FormatAsString();
                    cell.SetCellValue(address);
                }
            }
            var filepath = Path.Combine("D:\\test", "result2.xlsx");
            using (var fs = File.Create(filepath))
            {
                wb.Write(fs);
            }

生成的文件，在excel2007打开时，报错：
Excel在 result2.xlsx 中发现不可读取的内容。是否恢复此工作簿的内容?

The result2.xlsx can be opened correctly in Excel 2016. Can you test with Excel 2016 instead of Excel 2007?

我在office2010、WPS2024、 LibreOffice7.3.7.2测试了，都可以正常打开。

I don't have Excel 2007. This issue will be closed.
