Re-name users table column (db)

Hi community,

I’m really in need to change my wp_users database column names to suit my requirements.. For example – I want to change the column name “display_name” as “fullname”, “user_login” as “Login_username” etc..

I tried to find everywhere, but there are no such post I could find other than renaming the database prefix which I don’t need. I can even manually change in the database table if that solves my problem..

Please help.. I’d be thankful for volunteered helps.
