Create a grid with a for loop

I can’t figure this out.

Let’s say I have a movie clip of a square in my library and I want to use a for loop to create a 10x10 grid of those squares. How do I approach that?

Spacing each square horizontally or vertically isn’t a problem for me but I’m hung up on how to add 10 squares and then start a new line.

Can I do it all with a for loop?
