This problem is equivalent to understanding a certain category (the category of table data associated to a tabular algebra) which we introduce. The main result is that this category is equivalent to another category (the category of based posets associated to a tabular algebra) whose structure we describe explicitly.30 pages, AMSTeX, one inessential figureQuantum AlgebraCategory Theory16B50text
