Excel VBA宏求助：非必填列与必填列的关联校验问题

核心思路 #

不需要单独拆分Sub/Function，关键是提前完成所有表头的存在性检查并缓存对应的Range对象，之后在数据行循环中直接复用这些对象，既避免重复查找的效率问题，也能自然关联必填与非必填列的校验逻辑。

具体优化步骤 #

• 提前定位所有需要的表头列：在进入数据行循环前，一次性找到必填列company、fee的Range，以及非必填列gross fee的Range（不存在则设为Nothing）。
• 简化循环内的校验逻辑：循环时直接使用提前缓存的Range，判断非必填列的Range是否存在，存在则执行比对校验，不存在则跳过。
• 避免重复查找：原代码在循环内反复调用Find查找表头，既浪费资源又容易出错，提前缓存后能大幅提升稳定性。

关键优化点说明 #

• 缓存表头Range：在循环前一次性完成所有表头查找，避免循环内重复调用Find，提升效率与稳定性。
• 非必填列校验逻辑：通过If Not rngGrossFee Is Nothing Then判断列是否存在，存在则执行比对，不存在直接跳过，完美整合进必填列的循环流程。
• 简化错误处理：移除冗余的变量与重复代码，让逻辑更清晰。
