How can I make my table aligned?

When I run this code:

%Part A (matrix G)
clear all; clc;
%type rec0506c.dat %displays content in file
grades = fopen('rec0506c.dat','r'); 
fgetl(grades); 
fgetl(grades);
G = fscanf(grades, '%*s%*s%f%f%f%*s \n',[3,7])';
frewind(grades);

%Part B (textscan)
fgetl(grades); 
fgetl(grades);
C= textscan(grades, '%s %s %f %f %f %s' );
A= cell2mat(C(3:5)) ;
N = C{1};
I = C{2} ;   
fclose(grades);

%Part C (Means)
%what does enlarge matrix G by appndation mean/
clc;
studentmean = mean(G')';
exammean = mean(G);
overallmean = (mean(exammean) + mean(studentmean))./2;
R = [G studentmean];

%Part D (Table)
clc;
P = flipud(sortrows(R,4)) ;
[AVE,is] = sort(R(:,4),'descend');
NI = N(is);
IS = I(is);
lol =NI';
lol2= IS';
GI = [NI IS];
gprime = GI';
O= (num2cell(P));
L= [NI,IS,O]';
Lfake = [NI,O]';
%Lgy = [NI
%B= flipud(sortrows(L',6));
clc;
table = fopen('rec0506d.dat','w') ;
fprintf(table,'Name             netID        E1      E2      E2|            AVE \n ---------------------------------------------------------------------------------\n')
s= '%s    %s        %-1.0f %-1.0f %-1.0f| %6.2f \n';
fprintf(table,s, L{:})
%31.0f %7.0f %7.0f| %15.2f \n
%s= '%s     \n %s ';
%fprintf(table,s,gprime{:})

fprintf(table,'--------------------------------------------------------------------------------\n')
fprintf(table,'           exam_AV =      %6.2f  %6.2f %6.2f  | %6.2f  \n', [exammean,overallmean])
fclose(table) 
type rec0506d.dat

I end up with this: https://gyazo.com/2bed3c42308dede165e4761b6740d651

it's the second column that throws everything off. How can I resolve this?

Please do not force us to open strange looking links to understand your problem. You can post text and images in this forum directly.

Do you see, that your code is not readable? Edit it and use the "{} Code" button.

Click on links to dodgy websites? Why would I do that?
