Hi all , using some advices from previously asked questions , I used indexing to append values to a table that I am gonna write on Excel file :
if f1==1
Tout{1}=[filename;Tit]
else
Tout{f1} = [Tout{f1-1};filename;Tit]
end
writetable(Tout{end},'All.xlsx')
But I get the error
Error: Undefined function or variable 'Tout'.

you need to pre-allocate Tout, something like
N = appropriate value
Tout = cell(1,N);
before assigning values

Error: All input arguments must be tables.

I think because I wanted to include one line of only string :
I converted the filename into a table , but it's a 1x1 cell2table
Tout{f1} = [Tout{f1-1};filename;Tit]
so now I get this error :
Error: All tables in the bracketed expression must have the same number of variables.
because I wanted to divide between each Tit table that I was adding, there be one string filename. but it has no sense that I repeat the filename as many times as the Tit size.
