You can instruct the engine to search using one column or all columns in the condition part. Depending on the kind of patterns you are looking for.
A pattern can be formatted as a RULE or FACT, for example;
Rule format: If Product = Jacket Then Profit = High.
Confidence = 80%
Fact format: Most products where Product = Jacket have Profit = High.
Percentage = 80%
In this example the "If Condition" column is Product.
