Adding a pricing grid - size/quantity/price

Site URL: http://brownleepress.com

I'd like to add a pricing grid to my website, where I list quantities and prices for things, sorted by size. I like the situation on https://www.stickermule.com/products/die-cut-stickers ... is this possible? Maybe it's a thing already but I just don't know what to call it?

I don't need it to be hooked to my shop or anything. I just want to create something for reference.
