Don't think of rows/cols as two dimensions. Here's a MySQL table that looks up descriptions in a two-dimensional space. It should be obvious how to extend it to an arbitrary number of dimensions.
CREATE TABLE IF NOT EXISTS brlewis_map (
x integer NOT NULL, y integer NOT NULL, descr varchar (255) NOT NULL, PRIMARY KEY (x, y))
One of the demos at
http://www.webappcabaret.com/brl/p/brlewis/index.brl
uses this exact table.
