How to add a tree of clickable information to a JTable

I'd like to add a file-explorer type of drop down list/tree to a JTable
populated with Strings. When I click on a table cell which contains a
string of info, I'd like it to expand to show other information related to
the string. I'm not asking for any code solutions, but rather a pointer
about which type of built-in Java language feature(s) to use to accomplish
this goal. Thanks.
