OAF: Table/advanced table

Hi,

Hope some one will help me out in resolving the below requirement about how to do it in oracle OAF:

I had a employee table with name, salary, %increase, total salary and the table has only employee and salary information, this i have to show in a editable table format which i am able to show:

Here are the requirements:

1. when the user enters %increase the total should automatically calculate like (salary + (salary*%increase/100))

employee salary [%increase] total salary
======================================
abc 1000 2 1020
xyz 2000 3 2060

2. when the user enters total salary then %increase should automatically calculate

employee salary %increase [total salary]
======================================
abc 1000 2 1020
xyz 2000 3 2060
