Key data concept – narrow tables versus wide tables


Data tables are row-by-column matrices, and obviously they can range in size from one row by one column to many rows by many columns. You might have come across the colloquial expressions narrow table and wide table, or even narrow long table and wide short table. These concepts refer to the number of columns in the table, but not in a literal sense.
