title: Have a jcombobox filter a jtable
body: <p>following this tutorial  <a href="http://www.netbeans.org/kb/docs/java/gui-db-custom.html#enhancements" rel="nofollow noreferrer">http://www.netbeans.org/kb/docs/java/gui-db-custom.html#enhancements</a></p>
  
  <p>it shows how to use a textbox to filter out the master table. Could anyone instruct me on how to do a similiar thing but use a dropdown to test against a specific column?</p>
  
  <p>(ie a dropdown of countries, to filter by the country column?</p>
  
  <p>thanks</p>
