vertically aligned data using fprintf

data= 

1	0	-0.828330184322257	-1.90936748180674	-0.973747768469492
1	300	-0.838221643420248	-1.73368790711073	-0.694053671027946
1	600	-0.719016934251202	-1.77992572323036	-0.809246004716909
1	900	-0.685322042436873	-1.62664527333989	-0.659059040624753
1	1200	-0.598472883146815	-1.68630603450331	-0.631032590099370

The above data matrix is just a part of my orginal data file. I use the following code to print the data in a text file:

fprintf(fid, '\n');
fprintf(fid,'%02d        %d              %.3f            %.3f                        %.3f\n', data');
fclose(fid);

The printed results in a text file looks like:

01 0 -0.828 -1.909 -0.974

01 300 -0.838 -1.734 -0.694

01 600 -0.719 -1.780 -0.809

01 900 -0.685 -1.627 -0.659

01 1200 -0.598 -1.686 -0.631

As seen, the vertical alignment of the columns (except for 1st column) are not maintained due to the different size of 2nd column and the signs (+,-) of 3-4-5 columns. How I can print the vertically aligned data matrix of each column?

Use the width in the format specifier

data = [1        0       -0.828   -1.909 -0.974; ...
        1        300     -0.838   -1.734  -0.694; ...
        1        600     -0.719   -1.780  -0.809; ...
        1        900     -0.685   -1.627  -0.659; ...
        1        1200    -0.598   -1.686  -0.631];
fprintf('%02d      %-8d%16.3f%16.3f%16.3f\n', data');

01      0                     -0.828              -1.909              -0.974
01      300                   -0.838              -1.734              -0.694
01      600                   -0.719              -1.780              -0.809
01      900                   -0.685              -1.627              -0.659
01      1200                  -0.598              -1.686              -0.631
