If you have to display a overview of related data in a table,
you can use the CListView, create your view with table/tr/td tags
and implement db-queries in the view to display detaildata of the current (master-)record.
This little tutorial explains a way how you can retrieve more parameters from Yii::app()->user by adding a component that extends CWebUser and retrieves the user information from database table named User.
These features provide endless possibilities and unbelievable flexibility, but as current documentation does not give more than a few examples, it might be difficult to fully understand their internals and requirements.
