Sum multiple Columns formula

Hello,

 

I would like to sum mutliple columns in a table. For now, I simply did it like this:

As the amount of columns might vary from time to time, I aim to make it more flexible. In all columns that have to be summed the word "Capacity" will always appear in the first row. Is it possible to create a Column based on a formula in the Power Query Editor which automatically sums all Columns which have the word capacity in its first row?

 

Thank you very much for your help.

 

Best regards,

Jakob

Hi @JTR 

 

Can you promote the first row as header or you need the column names remain as Column1, Column2...? Here is one way if you promote the first row, my previous step is Change Type, you need to modify it accordingly

Table.AddColumn(yourPreviousStep, "Custom", (x) => List.Sum(List.Transform( List.Select( Table.ColumnNames( yourPreviousStep), each Text.Contains(_,"Capacity")), each Record.Field(x,_))))
