I have altered the user registration form and have made it dynamic with some more input fields. So, I have created a separate table in drupal database to store the additional details. Now, from my newly created table I want to display 2-3 fields on the main page. I have installed views module for this purpose. Now, in the views UI, I am not able to find any option to add fields from my newly created table (created in drupal database). Is this possible? The default options of user name, picture is present but the additional details which I have added is not showing up anywhere in the views UI. Do, I have to use views API and have to write code to incorporate this feature. Please suggest any other module which can be of use for me.
