% 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]';
D = [0.5 0.7 9.5 3.3 3.8 3.1 4.7 3.9]';
T = table(A,B,C,D);
% 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),[])
DD = reshape(T.D,length(x),[])
% plot
hold on

errorbar(x,CC,DD)

Error using errorbar (line 105)
X-data must be the same size as Y-data.

Do you mean something like this?
% 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]';
D = [0.5 0.7 9.5 3.3 3.8 3.1 4.7 3.9]';
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),[]);
DD = reshape(T.D,length(x),[]);
EE = reshape(T.E,length(x),[]);
% plot
hold on
hb = bar(x,CC);
errorbar(x-0.15,CC(:,1),DD(:,1),'o','Color','k'); %%%%%%%%%%%%%%
errorbar(x+0.15,CC(:,2),DD(:,2),'o','Color','k'); %%%%%%%%%%%%%%
text(x-0.2,CC(:,1)+DD(:,1)+5,EE(:,1))
