好的。我有点得意忘形这里，但这样做你是问（您可能需要调整它以满足您的特定需求。若要使用此代码，只需调用子“满足客户”。
你的原代码建议使用三个数组，Excel VBA提供了一些机制来完成你所寻求的任务，这些机制既易于使用又可能更高效。好像更多的代码，你会发现每个peice可能会更有意义，并且更易于维护。如果需要，您现在也可以重新使用其他操作的单个函数。
我也拉将范围和列索引编辑到本地定义的常量中。这样，如果需要更改各种行或列引用，则只需在一个位置更改值。
这不一定是最有效的方法，但最可能比使用最初提议的数组复杂。
我没有详尽地测试过这个，但它在最基本的意义上起作用。如果您有任何问题，请告诉我。
希望有所帮助。 。 。

您是否需要“最后”和“当前”数组来处理其他任何事情，还是仅仅为了生成“两个”数组？ –
您可以在Excel中使用ADO。这将很容易与查询：http://support.microsoft.com/kb/257819 – Fionnuala
