Why do I need rows and columns in LWC?

What does each row in a table represent?
It’s for assigning lodging, and each row will represent a room and each column for which the room can be assigned. It will involve drag/drop etc. I was hoping to make each row and each cell a component, so that data and logic could be encapsulated in each of those.
