Storing salt and hashed password

Is there a benefit to storing salt appended to hashed password in a single column of a table verses storing salt and hashed password in different columns of the table. The OWASP guide here http://ift.tt/Y7UIkC says 'Store the protected form appended to the salt as follows'

[protected form] = [salt] + protect([protection func], [salt] + [credential]);

Thanks
