I agree, aesthetically, that it would be nice to order the table entries, but the way tables work, the order is completely irrelevant. When you roll on the table, it picks a result completely randomly (according to each entries weight) and order doesn't matter. What would be really nice is to have rolls associated with a table (e.g. roll 3d6 on this table), and have modifiers (add +2 to rolls on this table). With those features, order would matter.
