Creating Dynamic Table & Data Populating

[Keisuke]

Hi,

I need to build a web application in VS2005 VB.NET that require adding/removing parameter.
Therefore the oracle database design needs to be dynamic & flexible.
I have already designed the database part, however the problem comes when I need to generate table & populating the group data from it to the display portion.

Illustration
Parant Group
Parameter 1

Sub Group of Parameter 1
Parameter 2
Parameter 3

Sub Group of Parameter 2
Parameter 4
Parameter 5
Parameter 6

Sub Group of Parameter 3
Parameter 7
Parameter 8

The generated table would need to look something like

How is this achievable?
Anyone have experienced doing this or has a solution please advise?
