This is what i have. (note: originally i have 7 columns but i have only shown just 2 columns for convenience)
'No.' 'Time'
'1' '0.000000000'
'2' '0.100209000'
'3' '0.199458000'
'4' '0.299589000'
'5' '0.399856000'
'6' '0.499050000'
'7' '0.599287000'
'8' '0.698449000'
'9' '0.798677000'
'10' '0.898885000'
'
'1000' '99.00000000'
Here is the code i use to extract
fid = fopen('eT1.txt', 'r');
data = textscan(fid, '%d%f%s%s%s%d%s', 'MultipleDelimsAsOne',true, 'HeaderLines',1);
fclose(fid);
But what i want only 1000 values extracted. In that case i need all the 7 columns but till No==1000. how to do that?

Assuming you only want 1000 rows and not just 1000 values (which is not a multiple of 7):
data = textscan(fid, '%d%f%s%s%s%d%s', 1000, 'MultipleDelimsAsOne',true, 'HeaderLines',1);

n=1000
data=cell(n,1);
fid = fopen('file.txt', 'r');
fgetl(fid);
for k=1:n
data{k} = fgetl(fid);
end
fclose(fid);
celldisp(data)

You forgot to attach your file. Are the single quotes actually in your file or not? Whynot just use a table:
t = readtable(filename);

readtable() takes alphanumeric values. It should be the easiest way, though it requires R2013b or later. You could speed things up (the back and forth question asking) if you would just attach the file, at least just a few lines of it.
