Creating a calculated column

Hi, I'm fairly new to Power Bi and I'm not understanding how to do this.

Let's say I have table (1) and I want to create table (2):
(1)Starting table

(2)What I want
I managed to create table (3), but I want to create a calculated column like the one in table (2)
(3)

I don't know how to summarize in a calculated column.
Any help would be greatly appreciated, 
thanks

    Hey Anonymous ,

     

    to get rid of rows, you always have to use Power Query. A calculated column just adds a new column, but it will not combine rows.

    In your case you need a group by with the following criteria:

    Then the result will look like this:

     

     

    Check the video I created on how to do that, it's pretty easy:

     

    If you need any help please let me know.
    If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍

      Thank you for your solution, I will try it out.
      Let's say I don't care about rows, i.e. I want every rows to display the sum of "Value" for every "Name", how would you do that?

        Hey Anonymous ,

         

        you can add a calculated column and ignore all the row context except for the Name. The following calculated column will do that:

        Total Value by Name =
CALCULATE(
    SUM( 'myTable'[Value] ),
    ALLEXCEPT(
        'myTable',
        'myTable'[Name]
    )
)

         

        If you need any help please let me know.
