Row level cascading in Apex tabular form

Question

Hi,
I have searched alot,but i am not able to find the solution
I have a tabular form and  having only one column say column A is dynamic LOV (Select col1 from lov_table will return values as 1,2,3........)
  When user press ADD ROW button
row 1 => column A display LOV as _1,2,3.... then if user selects  1
When user press ADD ROW button
row 2 => column A "should" display LOV as 2,3,.....
Anyone could help me out to solve this problem......
