下载JTable中的内容

Question

I want to show all the categories in the database in each line of a JTable i have done that. Now when i click on the each row of JTable i need to show the list of products under it (considered as child of the category) as a drop down not as a drop down list which closes automatically when focus is lost, but it should stay there until i click on minimize icon in the same row. It is just like expanding content. so i can expand all categories individually. The working is similar to JTree but i need it in JTable so that i can show more information on each row in a proper format. Any ideas ?
