I have a data table like this:

DataTable
AccountID BrokerA BrokerB BrokerC BrokerD
AccountA 0 0 27 0
AccountB 0 5 28 0
AccountB 177 1969 1749 400
AccountA 0 10 0 0
AccountB 5 60 0 0
AccountB 96 623 875 70
AccountA 0 10 7 0
AccountB 0 483 102 0
AccountB 70 180 358 33

I am trying to create this summary table:

SummaryTable
BrokerA BrokerB BrokerC BrokerD
AccountA 0 20 34 0
AccountB 348 3320 3112 503


Where the formula in the table body is looking at the Account a summing up
all values for each broker.

I thought I could do it with a formula.

Thank you in advance.
