Define the delimiter in your writetable call to be the tab '\t' character —

type('data.txt')
data 1,data 2,data 3
50,140,36
type('data_new.txt')
data 1	data 2	data 3
50	140	36
T1 = readtable('data.txt', 'VariableNamingRule','preserve')
T1 = 1×3 table
    data 1    data 2    data 3
    ______    ______    ______

      50       140        36  
writetable(T1, 'new_file.txt', 'Delimiter','\t')           % Write New File
type('new_file.txt')
data 1	data 2	data 3
50	140	36

I am not certain that it is possible to change the delimiter from a comma (,) to a tab except by writiing it to a new file.

EDIT — Corrected typographical errors.

Thank you for your reply. The table that is generated in the matlab workspace is fine. I should save the .txt as that table. Currently, the inside of the new .txt file (saved with writetable) does not match the table created on the workspace.

type('data_1.txt');
T1 = readtable('data_1.txt', 'VariableNamingRule','preserve');
writetable(T1, 'data_new.txt', 'Delimiter','\t');

What the file contains internally is irrelevant. It only has to produce the correct result when read.

If you want it to look like that internally, use the Contact Support link to submit an enhancement request. Include the URL of this thread in your note to MathWorks.
