Dependent Dynamic LOV lists in a table format

Question

I have a screen where the user can enter multiple rows into a tabular layout.
Three columns have LOV's where the selection in the first LOV should restrict the list in the Second LOV which will restrict the list in the third LOV. I think I could manage it if it were a single row of data being captured, but how does one reference the previous fields selection in the next field when using multiple table rows.
I have a db table which I think can drive the process, but I'm not familiar with the method in which to handle it.
Table: id, LOV-1 -value, LOV-2 value, LOV-3 value
So when user selects from LOV-1, only those LOV-2 values associated with LOV-1 that the user selected should be listed. And then LOV-3 values associated with LOV-2 selection should only be listed.
Can someone offer some insight or point me to an example?
Thanks

Answer 1

Has anyone been able to implement a series of dependent LOV's in a tabular report which is updateable?
I have a collection which I update 'onchange' if an LOV column is updated to retain the new value. I still have the issue of referencing the 'correct rows' previous LOV value to limit the next LOV's selection list.
Any suggestions on how to reference the previous column's value for the current row?
Desired process flow:
1 .user selects value 2 from LOV 1 [row 1]
-onchange, trigger submit of form back to itself updating the collection.
2. provide LOV 2 [row 1] with limited list of values based on selection in LOV 1 [row 1]
-onchange, trigger submit of form back to itself updating the collection with values of
row 1's LOV 1 and LOV 2
3. provide LOV 3 [row 1] with limited list of values based on selection in row 1's LOV 1 and LOV 2
Is there away to change the dependent list of values using a javascript function? Such as repopulate the LOV?
Help?
