For bar, groups are created organizing the data into a matrix. The rows correspond to x, and the columns correspond to each data series. See this example.
That means you will need to do some reorganizing of the data to get it formatted correctly to create a grouped bar chart.
% Set up the problem by recreating the table.
A = [ 0 0 1 1 2 2 3 3]';
B = ['0' '1' '0' '1' '0' '1' '0' '1']';
C = [2 11 32 33 38 31 47 39]';
T = table(A,B,C);
% use sortrows to organize data in an expected format
T = sortrows(T,["B","A"]);
% extract x values, group names
x = unique(T.A);
b = unique(T.B);
% Reshape the data based on the number of unique values in A
CC = reshape(T.C,length(x),[])
% plot
bar(x,CC)
legend(b)
