WordPress Installation Error

I Get this message: One or more database tables are unavailable. The database may need to be repaired

When I click on the word “repaired” I get this message:
To allow use of this page to automatically repair database problems, please add the following line to your wp-config.php file. Once this line is added to your config, reload this page.

define(‘WP_ALLOW_REPAIR’, true);

I have no idea how to fix this and I need major help please.
