VBA脚本输出异常：Description文件为空，求技术排查帮助

运行以下VBA脚本时，specification与summary文件可正常输出内容，但Description文件始终为空，尽管对应单元格存在有效数据。

原VBA代码 #

使用的数据表（products表） #

参数表（arguments表） #

核心问题 #

1. 判断逻辑反转：在Case Des, Summ分支中，代码写反了判断条件——当前是单元格为空时输出内容，但实际需求是单元格有值时输出单元格内容，为空时才输出副标题，导致有值的description单元格反而不输出内容。
2. 路径赋值不严谨：外层循环中仅当i=1/7/8时才赋值Path，但内层循环每次都依赖Path生成文件名，当i遍历其他列时，Path会保留上一次的值，可能导致文件写入错误路径。

修复说明 #

1. 修正判断逻辑：将Des/Summ列的空值判断反转，确保单元格有值时输出对应内容，为空时才输出副标题。
2. 拆分循环逻辑：将Des/Spec/Summ列的处理拆分为独立循环，避免路径混乱，确保每列都生成正确的文件夹路径。
3. 优化文件号获取：每次打开文件前重新调用FreeFile获取可用文件号，避免文件号冲突导致的写入失败。
4. 使用&替代+拼接字符串：VBA中&是更安全的字符串拼接运算符，避免数值类型导致的错误。
