How to get Entity Reference Autocomplete results to display in a table?
The first thing thats jumps out at me is that you have "Referencing Entity" rather than "Referenced Entity" in your views relationship.

Because you are showing  a view of content with the field, you are already showing the referencing entity. What you want is a relationship to the referenced entities.

Have you also got the views block to display on the correct content type?

You have the correct contextual filter set up (you can use "get content id from url" rather than raw value).

Make sure the block is shown in a region on all of the referencing entities content type.
