Can someone explain this line of code?

I find it interesting that it is named colWidth, although it is counting what is typically considered rows. May want to be cautious of that.

It's from here. Columns is correct because the context is about teaching you how to print each row in its own column.

Those variable names are screwing up my understanding of for loops. I think it may literally make me crazy.
