How to create “Add To Cart” or “Sign Up Now” button ?

Hi,
This is the kind of plugin I was looking for for my webpage. I tried to use it in woocommerce but I cannot put it in good use. The table it creates is nice, but there is no “Add to cart” or “Sign Up Now” or “Buy Now” button. Without it I cannot link it to the Cart page or the Checkout page. Can you tell me how to do it?
