dtdt's Issues

Generate the full decision table with all iterations (n^2)

In your example you have three conditions, so the mathematical table has 8 iterations of y/n.

Your example shows only 6, iteration 3 and 6 have the results of "buy ties?" included (cause they dont matter for the action outcome).

For folks unfamiliar with decision tables it might be confusing, a more detailed example or describtive information could help folks understand the concept of decision tables better (if they have not read up somewhere else about it).
