Add columns to tables with loops

I want to create a first column for my table, after a loop. I tried like this:

%N(mxn)
i=1;
while i<= size(N,1)
    capa(i) = fprintf('Bar #',int2str(i));
    i=i+1;
end

Furthermore I used sprintf.

The result in this case of three rows, it would be:

Bar 1
Bar 2
Bar 3

See this example

t = array2table(rand(3)); % example table
rows = compose('Bar %d', [1 2 3]);
rows = vertcat(rows{:});
T = [table(rows, 'VariableNames', {'labels'}) t];
