Matlab does not save the variable in each loop

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

Thank you , now it's giving me this error :

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.

Any opinions on this ?

Any help ?

How can I have different variable names in each row ? is it possible to use matlab structures?
