To access the Conditional Formatting window
Right-click on any cell (excluding heading row and numbered columns) in the Design view of the Format Editor window. The Conditional Formatting window opens.
Enter a condition to determine if the style changes listed in the Style changes box are to be applied or not. By default, the condition field is empty.
Click the Style Editor button to apply the changes. Any style changes made are then summarised and displayed in the Style Changes listing. By default, the Style changes listing displays No style changes.
