2. Multiple Layout within an expandable list

I am writing a program where I use an expandable list created from a
string array in an xml file and wish to have the program create the
children from an xml file string but display them in a table.

For example:

The parent group would be Comp Sci and the children group would be a
table with a headings row of Test 1, Test 2, Test 3, Test 4 with on
the next row the results and a final row of one cell for notes.

Sorry I could give a picture of what I want. Is this possible?

Thanks in advance
