Do not upload screenshots of data. These are useless for us. We cannot import a screenshot. We have no way to test code with a screenshot. We cannot tell if your data file uses tabs, or space characters, or what end-of-line characters it uses, or anything else about the file. Because a screenshot is not your data.
Please upload data in its original form by clicking the paperclip icon.

fid = fopen('temp5.txt','rt');
C = textscan(fid,'%f%f','HeaderLines',6);
fclose(fid);
Which correctly read all E-notation values in the file to import this numeric data:
>> C{1}
ans =
0
0.1
2.02
>> C{2}
ans =
0
0.00146
0.00591
Because you did not provide any sample data file I created my own, available at the link below:
