Table prefix issue while using relationship

[robincsamuel]

'columns' => array(
        'id',
        'username',
        'full_name' => array(
            'title' => 'Full Name',
            'relationship' => 'profile',
            'select' => "(:table).full_name"
        ),
    )

I'm facing issue with above column full_name. I use table prefix, and the issue is with aliasing.

r_ is my prefix, profiles is the relationship table.

WHERE r_users.id = full_name_r_profiles.user_id AND `r_full_name_r_profiles`.`user_id` is not null

Problem is,
for the first condition it used full_name_r_profiles and after 'AND' r_full_name_r_profiles.

Correct version is full_name_r_profiles.
