Option box to include # required as well as size

Hello,

I have a t-shirt order form. How do I add in my option box for t-shirt sizes the number of t-shirts they require in each size as an additional field?  Also how can I make the text boxes in the input tables wider so you can see the full names being typed in?

Thank you,

Lori
