First, no different in 1.1 than 2.0.
It is all about Object Oriented Programming(plus the additional difficulty
of sending the info to the web).
Imagin each cell in the grid to be an element in an array of rows.
Whatever you put in the cells is an object with some representation in the
DOM (Document Object Model) at the server (there is also a DOM at the
client (but this you access at the client in Javascript).
