Purpose? Is this information you want to display to the user? Are they purchasing the items that fill in the grid? Or is this a fixed grid of pre-selected items, where the user can make modifications to the individual items (like if you had 20 attributes that are grouped into 4 groups of 5 things each)?
Are there always going to be exactly 20 items in this category? What if a new supplement comes out that adds more - do you mind if the table gets taller?
