Creating a Table withJDBC and SQL - Java Database Programming Bible - page 183

Figure 5-1: TableBuilderFrame generates SQL from table entries.
TableBuilderFrame is, in turn, built around a Jtable, which has been customized by adding
JComboBox components as column editors for such fields as DataType.
The method setCommandListener() is called by the MVC controller so that TableBuilderFrame
can pass the controller the generated SQL command when the Create Table button bar at the bottom
of the frame is pressed by the user.
