How to Show Line Numbering Side by Side to Compare Two Sources?

Welcome to the forum, and thanks for your post.

I have reformatted the title of your post as a question in accordance with our guidelines:

Please feel free to adapt as you see fit. I also have added the line-numbering tag.

Would you care sharing your code please so we have something to work from? And perhaps a screenshot of the intended results as it is not clear (to me at least) what the intended result is.

You should then get help in no time.
