A summary column performs a computation on another column's data.

A formula column is a user-created column that gets its data from a PL/SQL function or expression, a SQL statement, or a combination of these. A formula column performs a user-defined computation on the data of one or more column(s), including placeholder columns.

Definitions:
Using the Conditional Formatting and Format Exception dialog boxes, you can specify output formatting attributes (font and color) for a selected layout object based on conditions that exist. The conditions that you define are called format exceptions.

Format triggers are PL/SQL functions executed before the object is displayed. The trigger can be used to dynamically change the formatting attributes of the object. The function must return a Boolean value (TRUE or FALSE).
