aggrid-groupingtable relation questions

First, is there any documentation that explains how to use an aggrid-groupingtable?
Next, can someone explain the different names of grids. For example, is an aggrid-groupingtable actually a Data Grid and is a Data Grid actually some kind of Servoy NG Grid?
Next, unlike other grids it looks like an aggrid-groupingtable gets it data using the name of a relation in its myFoundset property. The aggrid-datasettable, which I have used before, has no such column.
What I am attempting to do is to add an aggrid-groupingtable to an existing form that has lots of fields. The form's dataSource is a view called v_cash_deal_work whose primary key is the ID column. This ID is from the t_deal table and it uniquely identifies the current deal on that form.
The aggrid-groupingtable includes a column called fk_DealID, a foreign key to a t_deal.ID.
How do I construct a relation to get and show the set of products for the current deal to be displayed in the aggrid-groupingtable?
In other words, how do I tell the aggrid-groupingtable's relation where to find the t_deal.ID of the current record of the form it is in?
thanks,
Terry
