Below is a image of the WordPress admin user list:
All I want to do is add an extra column called add badges. Column value should be a link to a another page.
I tried editing core files but it ended up realizing it’s a bad practice since, because if I make changes I will lose the changes with the next update.

to get the table and $wp_list_table->display();
to display the table.
