you can alwsay put all of them in a single directory, then use dir to get all file names and iterate through all of them:
path = 'whatever';
files = dir(path);
% get rid of subdirectories and the likes of '.' and '..'
files = files(~[files.isdir])
data = table();
for i = 1:numel(files)
currFile = files(i);
t = readtable(fullfile(path, currFile.name));
findex = ['f', num2str(i)];
data(:, {[findex, '_1st'], [findex, '_2nd']}) = t(:, 1:2);
end
