Excel-如果在另一列中找到内容，则格式化单元格

Question

I have two columns of numeric values in Excel. This is a task list, column A is the task number, column C shows the number of any tasks that must be done before this task. Both columns are formatted as "General".

I want to highlight cells in column A that are listed as parents in column C. In some cases, a task might have more than one parent so the cell might have more than one number in it:

6, 17, 105

My data spans from rows 6 through 1004 and I've tried the following:

=ISNUMBER(SEARCH($A6,$C6:$C1004))

That works fine in other situations when I'm dealing with text, but not when the data is numbers. At least that's my theory for why it's not working here.

I've tried searching here and a general web search, but all the answers seem to apply to text data not numbers. How can I accomplish this with numeric data?

Edit:

Here's a screenshot of some of the data:

First column is the task number, third is a listing of "parent" task for the given task. For example, looking at task 81 at the bottom, it can't be done until tasks 17, 64 and 84 are done. What I want to do is format any task number that has children. So, in the example I just mentioned, task 84 (near the top) should be colored differently since it has a "child".

Answer 1

Please clear any existing CF from ColumnA, select it and HOME > Styles - Conditional Formatting, New Rule..., Use a formula to determine which cells to format and Format values where this formula is true: :

=AND(A1<>"",MATCH("*"&A1&"*",C:C,0)) 

Format... , select choice of formatting, OK .

Assumes all of ColumnC is Text format.

If that does not suit please (a) ensure your text and your data sample are compatible, (b) provide the sample in Text format (not only image) and (c) indicate exactly what you would like highlighted.
