Sum of specific row of all the coulumns

I am trying to get the totals in row 7 for all the columns (marked in red).

Answer 1

[Ameer Hamza]

Run this example

t = {'row1', 100, 20, 35;
     'row2', 200, 13, 34;
     'row3', 450, 24, 24;
     'row4',  20, 12, 10};
t = cell2table(t);
t{end+1,2:end} = sum(t{:,2:end})

Answer 2

Hi, thank you for tips.

I did not use the second code t = cell2table(t);

[Ameer Hamza]

Yes, that was just an example to create a table. If you already have a table, then there is no need.

That's correct. Thank you.
