If I'm understanding your question, you're looking for only the properties of classes in a specific diagram to be displayed in a generic table, which is possible.

You can create a smart package, and either manually populate that smart package or create a query that dynamically calculates the contents to contain the properties you're looking for.

Then set that smart package as the scope of the generic table and properties as the type of elements to display. That will give you your first column.

For the second column, depending on the relationship you're using to create the "mapping" of properties, you can create a custom column in the generic table to show elements related to the property using that particular type of relationship.
