It looks to me like you're just repeating the contents of each row. "A B C" becomes "A B C A B C" (I just took out the repeating letters to make it a bit easier to read). Each row seems to do exactly that.

But that doesn't match the columns you listed in your output.

So, I really can't tell what you're trying to do here. If it's just repeat a value, then just add the value (as a string) to itself (as a string), and you'll have it.
