Custom Table

[#1]

Hi

I have a scenario where I need to calculate 2 extra field values in a straight table with available other field values, I want to do it in the UI itself I don't need at script level.

problem: I have fields like Scenario, Type, Year, Value. from these fields I want to create a straight table like below , here Medium-to-small rate is the fraction of Mediumvalue/Small value.for  Small-to-Large rate   formula is  Small value/Large Value.

How to create it. please help me on this.
