G = struct('ones',{1 1 1 1},'twos',{2 2 2 2}); % for example
T= struct2table(G);
c=1:height(T); % use height
c=c';

T.new_column = c

T = 4×3 table
    ones    twos    new_column
    ____    ____    __________

     1       2          1     
     1       2          2     
     1       2          3     
     1       2          4

thanks but it's possibile di move c in the first column?

Hi @Luca Re,

Yes, it is possible to move c to the first column by doing the following:

%Using the previous code attached by Voss
G = struct('ones',{1 1 1 1},'twos',{2 2 2 2}); % for example
T= struct2table(G);
c=1:height(T); % use height
c=c';
T.new_column = c;

%Specify the order of the columns
order={'new_column','ones','twos'};

%Reorder them according to the order specified above
[~, ind] = ismember(order, T.Properties.VariableNames);
T_reordered = T(ind,order);

Hope this helps!

thanks

this is not cotrrect

the last element moved to first place

[shamal]

this is better :

T = [T(:,25) T(:,1) T(:,2) T(:,3) T(:,4) T(:,5) T(:,6) T(:,7) T(:,8) T(:,9) T(:,10) T(:,11) T(:,12) T(:,13) T(:,14) T(:,15) T(:,16) T(:,17) T(:,18) T(:,19) T(:,20) T(:,21) T(:,22) T(:,23) T(:,24)];

[Is it] possible [to] move c in the first column?

Yes, see below:

G = struct('ones',{1 1 1 1},'twos',{2 2 2 2}); % for example
T= struct2table(G);
c=1:height(T); % use height
c=c';
T.new_column = c;
T = T(:,[end 1:end-1])

T = 4×3 table
    new_column    ones    twos
    __________    ____    ____

        1          1       2  
        2          1       2  
        3          1       2  
        4          1       2
