You can display data from two models in the same table using MODEL_LOOKUP. Are you familiar with this function and how it works?

Yep. Thanks Stephen. I have used that and it works great. My explanation of what I was trying to accomplish was a bit flawed. Instead of showing data from two models in the same row, I want to show Rows from two different models in the same table. Say I have a custom object called “incoming mail” . I have a separate custom object called “outgoing mail”. They are both children of Contact. I would like to display rows from both and sort by the created date field in a single table. There are other examples like displaying tasks and custom object records in the same table for a given contact. The idea would be for records from both objects to appear in the same table and be sortable by some common criteria like created date or a Ui only formula field.

I see. Thanks for clarifying. 

@Raymond Internally we are referring to this feature request as “Union Models”, and it is on our Roadmap. 

Great! Thanks!

I have several use cases for this as well.

Is this still on the roadmap? @Rob_Hatch

Honestly it is not currently on our roadmap. The “adopt rows” action can be used to combine models that have similar field structures. In addition Jer published a custom extension of adopt rows that allows more flexibility in his “Smart Adopt” skuid labs experiement. Look here. skuid-labs/experiments/snippets/smartAdopt at master · skuid/skuid-labs · GitHub

Depending on what you are trying to accomplish, model lookup function is also good for combining info from two or more separate models into a single model.
