如何从两个不同的工作表中搜索数据并将它们复制到第三个工作表？

Question

Excel 表格布局

问题：

我必须从两张纸的第一列中找到所有字符串的超集。这些可以存在于一张或两张纸中。根据存在的字符串，将该字符串复制到第三张纸上。然后从一个或两个工作表中复制下一列中的数据。然后找出区别。重复。如果两个工作表中都存在字符串，则此代码有效。如果第一列中的字符串不存在于其中一个或两个中，我该如何使其工作？我想包含两张表中的所有数据。

这是代码：

请帮忙。

试一试。该策略是在缓冲区中收集所有唯一的字符串值并将它们的行值存储在索引缓冲区中（假设一个字符串在一张纸上只出现一次）。然后从索引缓冲区中获取所有行值并将该行中的值复制到 ws3。 注意：我将循环和 lastrow 计数器的类型替换为 long。
