Printing just one column in text file in scientific notation

I am creating a text file with two columns of data using the following scheme:

data = [a b]
datafile = sprintf('file_%s.txt',label);
fileID = fopen(datafile,'w');
fprintf(fileID,'%f %f\n',data');                                             
fclose(fileID);

I want the first column to be just the regular numbers, but the second column has very small values, so I want those printed out in the text file in scientific notation. How would I apply scientific notation to just that column? So when I open the text file it looks something like this (numbers arbitrary):

110.51 1.2222e-13
111.50 1.3897e-13
112.49 1.2342e-14
113.48 8.8123e-15

Thanks!

>> ab=[110.51 1.2222e-13
111.50 1.3897e-13
112.49 1.2342e-14
113.48 8.8123e-15];
>> fmt=['%8.2f %12.5e \n'];
>> fprintf(fmt,ab.')
  110.51  1.22220e-13 
  111.50  1.38970e-13 
  112.49  1.23420e-14 
  113.48  8.81230e-15
