V92: Angular data table join representation.

The following tutorial from the Angular project Github page is a nice guide on how to work with data tables:

https://github.com/OneIdentity/IdentityManager.Imx/tree/v92/sdk_samples/03_using_data_tables

It shows a tabular representation of a simple table with a selection of its fields.  It is also pointed out that data tables offer a lot of possibilites and a look at the code confirms that fact. But , alas, it is not yet documented.

My question is, does anybody has an example on how to include fields from different tables linked by a FK? My case: I want to show some fields from the GAPUser table and a column with their corresponding SKU.

Thanks!
