Purchasing Table

I have an e-commerce clothing store and I am wanting a table on my [login to view URL] page (not sure if this is the correct word I am looking for) which will allow my customers to purchase various sizes of a particular product all in one click. I will try and visually create the table I am looking for: Color | XS | S | M | L | XL | Above is a visual of the purchasing module table. Where the word "Color" is, I would want that to be a dropdown menu so that the customer can choose which color they would like. And under the sizes I would want input text boxes so that the customer can input their desired quantity for each size. I have attached a jpg of the purchasing module I am describing. You can also see the exact purchasing module that I would want live at this link (just scroll down towards bottom of product info page): [login to view URL] The best part is that I own the website at that link, so I already have the module installed on one of my sites. So you will have access to all of the pages in which the code was already written. I'm sure this should be very helpful.
