Creating text file with columns of data

How do I create a text file with two columns of text correspond to columns of data?
I currently have
data = [a b];
% a and b are columns
fileID = fopen('textfile.txt','w');
fprintf(fileID,'%f %f\n',data);
fclose(fileID);
This creates two columns in textfile.txt, however, all of the "a" data is listed before the "b" data, instead of in 2 columns with the separate data. How do I get the proper data in each respective column of the text file? Thanks

In this case, you can use
fprintf(fileID,'%f %f\n',data')

Do you have an idea if I can also save additional values in the text file?
a = [1;2;3;4;5];
b = [1;2;3;4;5];
data = [a b];
fileID = fopen('textfile.txt','w');
for i = 1:3
fprintf(fileID,' %d %f %f\n',i, data');
end
fclose(fileID);
Here is a picture of how the final result file should look like:
