A dice table is a direct translation of a gaming table from a book, where the table has a stated dice expression, and each entry has a numeric range. Most tables can now be taken as is from published sources. Also, if a message from a randomly rolled table contains a dice expression, like Found 2d8 scrolls, the expression is automatically substituted. Finally if a message contains something like: You found a [wolf/fox/badger]. The displayed message will only include on of those entries.
