Function for role

Hi,

i would like to add datatables as custom capability to user role editor plugin(i.e. give access to datatables to specific user group) but i’m not sure what function i should use.

This tutorial gave me basic idea:
http://shinephp.com/user-role-editor-wordpress-plugin/
– but i found few functions and i’m not sure which one i should use.

I would love to see this as feature for User Role Editor plugin(for example WooCommerce or Master Slider have custom capabilities code added) but function name will be nice too :>

Thanks in advance.
