How can I set the table parameter in .txt output

I want to wirte a txt file which its elements space will be exactly 2 space. For example:

12667 576614.0000 3723897.0000 852.0000 6.0000 1750.0000

The code i wrote is the following:

FID=fopen('Header.txt','w');

fprintf(FID,'%i %3.4f %3.4f %3.4f %3.4f %3.4f\n',Table); (Table is the 6*100 matrix I wanna to write)

fclose(FID);

My problem is that the output txt file elemnts space are 1 instead of 2 (12667 576614.0000 3723897.0000 852.0000 6.0000 1750.0000)

How can I modify the code?

Thanks

Because you didn't tell Matlab to use 2 spaces in the FormatSpec. Compare the two versions below (the second line is to provide a scale to check for double spacing).

data=[12667  576614.0000  3723897.0000  852.0000  6.0000  1750.0000];

fprintf('%i %3.4f %3.4f %3.4f %3.4f %3.4f\n',data);fprintf('%d',mod(0:80,10))

12667 576614.0000 3723897.0000 852.0000 6.0000 1750.0000
012345678901234567890123456789012345678901234567890123456789012345678901234567890

fprintf('%i  %3.4f  %3.4f  %3.4f  %3.4f  %3.4f\n',data);fprintf('%d',mod(0:80,10))

12667  576614.0000  3723897.0000  852.0000  6.0000  1750.0000
