Table did not show correctly after converting from cell array by using cell2table

data = [32 47 51 41 46 30
46 38 34 34 52 48
48 38 43 41 21 24
25 29 33 45 51 32
32 27 23 23 34 35  ];
v = reshape(data,1,[]);     % reshape array (matrix)  to vector
nrClass = 5;             % 5 classes 
width = round(length(v)/ nrClass);  
str = sprintf('Class %d - %d \n', min(v), min(v) + width );
f =  length(v(  v <= ( min(v) + width ) ) );
C = {str, v(  v <= ( min(v) + width ) ), f };
for i=2:nrClass
    % Expand size by assign data to a cell outside the current dimensions
    C{i,1} = sprintf( 'Class %d - %d\n', min(v) + (i-1)*width, min(v) + i*width  ); %class boundaries
    C{i,2} =  v(  v > (  min(v) + (i-1)*width ) & v < ( min(v) + i*width  )  ) ;  
     C{i,3} =  length(C{i,2} ); % frequency
end
C13 = C(:,1:2:3)      % Only column 1 and 3, or C13 = C(:,[1,3]) also works

% Convert the cell array, C13, to a table and specify variable names
T = cell2table(C13, 'VariableNames',{'Class' 'Frequent'})

Output:

T =

       Class       Frequent
    ___________    ________

    [1x15 char]    6       
    [1x14 char]    5       
    [1x14 char]    6       
    [1x14 char]    3       
    [1x14 char]    5

So what is the "correct" table? What are you expecting?

It should show some thing like:

                     frequent
                     ________

    Class 21 - 27    6       
    Class 27 - 33    5       
    Class 33 - 39    7       
    Class 39 - 45    3       
    Class 45 - 51    9

The table seems to be fine, only the output suffers from the line breaks in the strings. So try to omit them:

data = [32 47 51 41 46 30; ...
        46 38 34 34 52 48; ...
        48 38 43 41 21 24; ...
        25 29 33 45 51 32; ...
        32 27 23 23 34 35  ];
v = reshape(data,1,[]);     % reshape array (matrix)  to vector
nrClass = 5;             % 5 classes 
width = round(length(v)/ nrClass);  
str = sprintf('Class %d - %d', min(v), min(v) + width );
f = length(v(v <= (min(v) + width)));
C = {str, v(v <= (min(v) + width)), f};
for i = 2:nrClass
    % Expand size by assign data to a cell outside the current dimensions
    C{i,1} = sprintf('Class %d - %d', min(v) + (i-1)*width, min(v) + i*width); %class boundaries
    C{i,2} = v(v > (min(v) + (i-1)*width) & v < (min(v) + i*width));
    C{i,3} = length(C{i,2} ); % frequency
end
C13 = C(:, [1,3]);
T = cell2table(C13, 'VariableNames', {'Class' 'Frequent'})

It works now. Thanks to @ Jan Simon
