[rules-users] Multiple Excel decisiontables - a bug

[Swindells, Thomas]

My advice is always to include a rulename (NAME) column and explicitly specify all the rule names.
That way the name of the rule is deterministic and doesn't suddenly change if someone happens to insert a rule in the row above - this is particularly useful if you log or audit the rules that have fired.
