Display tables ina tree structure

[GrahamL]

Hi
I have a need to to display a set of tables as a tree widget, such that each row in the tree is a table.
Expanding one of these rows should show the number of rows and expanding this should show a set pairs of items showing the column name and cell value.
eg
+cars
+1
model ford
colour red
+motor cycles
+1
make Triumph
cc 1000

Has anyone done this before? or has anyone any advice on how to approach this problem

Thanks in advance
