% Set up the problem by recreating the table.

E = ["Q1" "Q2" "Q1" "Q4" "Q1" "Q1" "Q2" "Q1"]';
T = table(A,B,C,D,E);
% use sortrows to organize data in an expected format
T = sortrows(T,["B","A"]);
% extract x values, group names
x = str2num(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),[]);
