Drill down table for a table of contents

CDeCinko

I'm looking for ideas/examples of how to handle data that is basically a table to contents, a drill down to details.

Initially the user would see the top left sections (section number and title). Click on a row and that section and title become the header for another table that contains the sub-sections (i.e. 1.1: Title for one dot one, 1.2: Title for one dot two) each a row of the table. Then, when you click a sub-section you see the detail page (in a dialog), that I can handle.

I've seen an example where one datatable is nested within the main datatable, but it looked awkward. You have multiple search boxes and column heads. Could be confusing to the user. I want only one datatable visible at a time. It's either populated with top level sections or second level sub sections.
