You use the decision table editor to create and work with
decision tables and use the special facilities provided.
Decision tables
A decision table groups rules that have similar conditions
and actions, and helps you spot problems such as overlaps and gaps
among the rules.
Adding and populating rows
You can add new blank rows, partially-completed rows and
Otherwise rows to a decision table. You can also move, split, merge
and delete rows, and populate them with values from an enumerated
domain.
Defining preconditions
You define preconditions to create variable definitions
that are available throughout the decision table and conditions that
must be satisfied before the decision table is executed.
Viewing rule details
You can view the details of a rule in a decision table
row by viewing a tooltip or by enabling the display of a dedicated
viewing pane below the decision table editor.
Viewing the decision table as a spreadsheet
You can display a decision table in a spreadsheet view
if the decision table has two condition columns and one action column
and the structure of the decision table is symmetric.
