Make a table with variable names which are saved as strings.

Let's assume that there are data files having a column of nubmers.

abc.dat

cdc.dat

usa.dat

I'd like combine them into a table.Can I use the file names as variable names?

ex) table T =

abc cdc usa

10 100 5

20 200 10

30 300 15

40 400 20

50 500 25

Matlab table is great for handling my data, but I am struggling to name variables.

I was looking at the 'eval' function, but it was not recommended from many thread here.

dinfo = dir('*.dat');
filenames = {dinfo.name};
T = table();
for K = 1 : length(filenames)
  thisfile = filenames{K};
  [~, varname, ~] = fileparts(thisfile);
  thisdata = load(thisfile, '-ascii');
  T.(varname) = thisdata;
end
