Table is not displaying cell arrays

I had a question because I was doing the tutorial on http://www.mathworks.com/help/matlab/ref/polyfit.html and their table displayed everything in coloumns, but mine just stayed as cell arrays. How do I display them like in the tutorial?

I get this:

          X                Y             YPrime        YDiffierence 
    _____________    _____________    _____________    _____________

    [1x10 double]    [1x10 double]    [1x10 double]    [1x10 double]

I want something like this:

 X        Y          Fit         FitError  
    ___    _______    __________    ___________

Just use the example of the link

x = (0:0.1:2.5)';
y = erf(x)
p = polyfit(x,y,6)
f = polyval(p,x);
T = table(x,y,f,y-f,'VariableNames',{'X','Y','Fit','FitError'})
