aligning data for fprintf

for j=1:2
[a(j),b(j)]=size(char(FileName(:,j)));   % b=[38 38]
[c(j),d(j)]=size(char(FileName2(:,j)));  % d=[38 38]
first_space(j)=b(j)+4;
second_space(j)=d(j)+8;
end

fprintf(fid,'%*s %*s\n',max(first_space),'  G',max(second_space),'   G');
fprintf(fid, '\n\n');
for j=1:2
fprintf(fid,'%s  %.1f  %s  %.1f\n', FileName{:,j}, data1(j), FileName2{:,j}, data2(j));
end

The above codes created the output txt file with aligned output data if the length of the Filenames are the same. For example:

FileName =

  1×2 cell array

    {'COD0MGXFIN_20210890000_01D_05M_ORB.SP3'}    {'COD0MGXFIN_20210900000_01D_05M_ORB.SP3'}
	
    FileName2 =

  1×2 cell array

    {'COD0MGXFIN_20210920000_01D_05M_ORB.SP3'}    {'COD0MGXFIN_20210930000_01D_05M_ORB.SP3'}

If these FileNames are used, there is no problem for the alignment. I attached the output file (output_aligned.txt)

But, when the length of Filenames are different, the alignment cannot be maintained with the above codes. For example:

FileName =

  1×2 cell array

    {'COD0MGXFIN_20210920000_01D_05M_ORB.SP3'}    {'COD20714.EPH_M'}

FileName2 =

  1×2 cell array

    {'COD0MGXFIN_20210890000_01D_05M_ORB.SP3'}    {'COD20720.EPH_M'}

When using the above FileNames, the output file doesn't aligned. I attached the output file (output_non_aligned.txt) created the second part of above codes. How can I modify the above codes to write consistently aligned output regardless of the length of FileName and FileName2?

Here is ax example

a = rand(10,1)*1e4;
sprintf('a = %7.2f\n',a')

ans = 
    'a =  169.57
     a = 5470.00
     a = 6023.50
     a = 7339.91
     a = 2607.20
     a =  630.21
     a = 2342.76
     a = 3390.90
     a = 9812.91
     a = 9146.70
     '

Use "\t" to create tabs?

Could you show me this modification using the above codes to be more specific?
