The choice of simple SQL will not work for you in this scenario. Although quite capable of producing formatted output, the nesting here would cause the issue. Try a select along the lines of:
select name || ' ' || lpad(emp_no) from emp
By using this you can get out the output you need. Now to get the nested details you would need to use something like PL/SQL, where you can use some looping to produce the necessary output and using DBMS_OUTPUT. This should provide you with the flexibility to produce what you will need.
