Inventory Availability by Lot No ?

Hello Experts

I have develop page bind with item ledger entry table i am trying to display the following fields on my page 

Item NO. , Lot No, LocationID and quantity from item ledger entry table on my custom page.

It is working fine but now i am trying to stop the line repetitions.

EG;

Item No.         Lot No.            LocatonID           Quantity

ITM-001          lOT-01            GREEN               2

ITM-001          lOT-01            GREEN               2

ITM-001          lOT-01            GREEN               3

ITM-001          lOT-01            GREEN               1

Now i am trying if item no , lot no and locationid is same then just display the line one time ? 

Just ignore the quantity because it is calculating perfectly just want to show the line one time .

Is there any possible way to do it if yes then how ?

That what i want to achieve 

Item No.         Lot No.            LocatonID           Quantity

ITM-001          lOT-01            GREEN               8
