How to validate input field values in communitybuilder registration from table

Hello;
Please help me on my problem.
I have a table that contains names of people that allowed only to register.
Now in the community builder registration field, if the user entered name in the name field and that name is not on the table automatically it will not allow to register.

Please help me.
Thanks in advance
