Your question is a bit vague, but let me try to help you.

To see the newly added table (entity) in your Published Odata Service, you first need to add it to the Entities which the Odata Services publishes.

Furthermore, you need to verify if the right access rules are set on the entity, so that the user role which is allowed in the Odata service has also read rights on the Entity itself.

Hope this helps.

After you add new entities to existing OData-publish you should first deploy your application to env, and then in application where you wanna use it you need to update your OData-consume service
