You do not have write permissions in the current folder. This is solved by specifiying a valid folder:
folder = tempdir;
fname = fullfile(folder, 'newfile.xlsx');
save(fname, 'Table3');

i wrote folder = tempdir; fname = fullfile(folder, 'newfile.xlsx'); save(fname, 'Table3'); file_location = which('newfile.xlsx') and the file that contains the table does not appear after

@mohammed: The file is saved in the folder, which is defined by the tempdir command. Type this in the command window:
tempdir
Of course you can use any otehr folder also, but I could not guess which folder you want. Therefore I've chosen tempdir as example:
folder = 'C:\Data\YourFolder\xyz;
fname = fullfile(folder, 'newfile.xlsx');
save(fname, 'Table3');
You can use uigetfolder also to select a folder in a GUI, or the output of userpath.

Also, if you mean "table" as in the data type whose class is table, don't use xlswrite, use writetable.
