Best method to align text in a textarea?

Hi I’m adding a cool copy to clipboard feature (first picture) to my web site and I’m having problems aligning the copied text. The second picture shows what I get. I’m putting spaces in the code but I know that will never work since the values will be changing. I think I need to use tables but I wanted to ask if they will work in a textarea before I spend 10 hours trying different things.

If It does work, can someone show me how to insert them into the textarea?

I would like the copied text to look like picture 3. I have tried to insert my code into this post using blockquote but it does not seem to be working in preview - in case it is not 4th picture is the code as I have it now…
