Create another top level "working" assembly and assemble your bracket asm into it along with the table. Add the working assembly to your drawing and create views where it's needed.
Alternate1: Add the model of the table to your drawing and add the views where it's needed. Place an opaque view of your bracket on top of it. Align the views either by a common coordinate system or via drawing grid coordinates.
Alternate2: Create draft entities of the table either by converting a view of the table to draft entities or by exporting a view of the table to DXF and importing it back in. Group the entities, remove the table model from the drawing, place an opaque view of your bracket on top of it. Lightweight but the table will not update to any changes.
The first method, in my opinion is the best along with simplified reps. No external references but it does require the table and the "working" assembly to be in the drawing. Alternates 1 and 2 have their drawbacks and may not work for some view angles/geometry.
