How can I fix the alignment

The first 10 answers are vertically aligned in a way and the remaining values in another way. How can i fix that?

Here is the program:

nn=length(0:10:720);
P=zeros(nn,1);
V=zeros(nn,1);
x=zeros(nn,1);
alfa_cont=zeros(nn,1);
for alfa=0:10:720
    cont=alfa/10+1;
    cos_alfa=cosd(alfa);
    alfa_cont(cont)=alfa;
    x(cont)=76.8*((1-cos_alfa)/2+0.28/4-(0.28/4)*cos_alfa^2);
    if (alfa<=180)
        P(cont)=0.9;
    elseif (alfa<=360)
        P(cont)=320.612/((x(cont)+8.93023)^1.32);
    elseif (alfa<=540)
        P(cont)=1119.9/((x(cont)+8.93023)^1.24);
    else
        P(cont)=1.1;
    end
    V(cont)= 0.0448882+x(cont)*pi*(80^2)/4*(10^(-6));
end
figure(1)
plot(V,P,'-r'),title('Diagram P-V'),xlabel('Volume [l]'),ylabel('Pressure [bar]'),grid;
fprintf('\n')
fprintf('alfa\t\tx[mm]\t\tP[bar]\t\tV[l]\n')
fprintf('%-6.4f\t\t%-6.4f\t\t%-6.4f\t\t%-6.4f\n',[alfa_cont x P V]')

This does it

    fprintf('%8s\t\t%8s\t\t%8s\t\t%8s\n', 'alfa', 'x[mm]', 'P[bar]', 'V[l]' )
    fprintf('%8.4f\t\t%8.4f\t\t%8.4f\t\t%8.4f\n',[alfa_cont, x, P, V]')

        alfa       x[mm]      P[bar]        V[l]
      0.0000      0.0000      0.9000      0.0449
     10.0000      0.7455      0.9000      0.0486
     20.0000      2.9447      0.9000      0.0597
     ....
    100.0000     50.2820      0.9000      0.2976
    110.0000     56.2807      0.9000      0.3278
    120.0000     61.6320      0.9000      0.3547

Mixing tabs a spaces is not robust. Depends on the settings of the tabs-positions.
