Render extra columns from COLLECTION_ATTRIBUTES on index page dynamically during runtime without code deployment

Created by: malaya7

Hi, I'm using this library for a project working on, and would like to be able to have extra columns show up on the index page without making code changes and deployment

Example: http://localhost:PORT/?extra_columns=id expected: column id will show up on the subsequent requests

PS: this is my first time working with ruby and rails, open for feedback and comments

Thanks.
