要创建格式化的excel文件，请执行以下操作：

那么，我如何在excel文件中对一个地区的每笔销售的详细信息进行排序？

如果有人需要解决类比问题，我用这段代码实现了目标：

        int currentId = -1;    // current sellID  
        int detailCount = 1;
        int beginSumLine = currentXLLine+3;
        for (int i = 0; i < dt.Rows.Count; i++) 
        {
            if ((currentId != (int)dt.Rows[i][0])) 
            {

                if (i != 0)
                {
