Novice question about table in SQL

I have installed personal edition of oracle on my computer, I know to find all of the tables in my database I use select * from tab;  

I wish to create a table then add rows to it latter, When I use such has

SQL> SELECT * FROM cd ;

I get no rows selected,

How can I get to see the contents of which my table is made up, such has my cd table below, if I have not put in any information in to the rows of the table , has I may forget how my table is made up

CD_NAME CD_ARTIST CD_LABEL
