如果A列的单元格值包含B列的单元格值，则A列的单元格值将更改为B列的单元格值。

If the cell' value of A Column contains the cell's value of B Column, the cell's value of A column change to the cell's value of B column.

您能找出答案吗？通过代码来解决这个问题?? ...

Could you figure it out by code that problem??...

目标：将A列的单元格值更改为B列的单元格值
（如果包含B列的值）
而且，我想利用 for -next！

AIM: the cell's value of A Column change to the cell's value of B Column (If contains the value of B column) And, I want to make use of "for -next"!

请帮我做到！

评论得很重，所以您知道发生了什么:)只需滚动一下就可以看到它。

Heavily commented so you know what is going on :) Just side scroll to see it.

您将需要定义一些变量才能使其正常工作。我把您需要更改的所有内容都放在一个地方。

You will need to define some of the variables to make this work correctly. I have put everything you need to change in one place.

Sub searchSegment()
' loops through all cells in column A, compare segements of cell string to column B, and if found replace column A with column B data
