Joepiooo on "[Plugin: Football Pool] Export ranking to a database table"

Ok I see...

I´m using a script from DataTables.net to get ranking. It is a very nice Jquery tool with pagination, search, and select options.

I got it working with pool_wp_scorehistory table but the output for username is the user_id from pool_wp_scorehistory and I want it to be the display_name from wp_users...

How can I do that wihtin this script:
