Create a cumulative table over the years

[Anonymous]

Hello, 

I have a very specific question: 

I have a datatable for 2020 and values that I want to be repeating fo the coming years 

For now I have only the grey table for 2020, and I want to create the whole table for the next 5 years

But I also need to consider (for exemple saying 2022) the figures from 2020 and 2021

So I want to create inside Power Query (Or Power BI Desktop) the Cumulative Column: Once a value is added, it will be repeated every year at the same date but it will be taking into account the new values (in orange and yellow) 

I hope I was clear enough, 

Thanks in advance, 

Constance

I think you are going to have to give a bit more info. I cannot tell how all of the non-gray data was created. Please see instructions below.
