How to store two tables resulting from a for loop

Hi guys,
I have a for loop with two iterations, and each iteration results into a table.
I would like to know whether it is possible to store the two tables coming out of the for loop such that I do not get the table from the first iteration overwritten from the second one.
Thanks for your help in advance.

Yes, with something like this
for jj = 1 : 2
T = something;
filename = sprintf( 'myfile_%d', jj );
writetable( T, filename )
end
if I understand your question correctly

Yes, that essentially what I want. Is there a way to 'save' the results without actually saving a .txt file? Like the same way you would do it in a vector:
for i=1:2
y(i)=i+2
end

Ok, I now understand what you want.
numIters = 3;
tables = cell(numIters,1); % A cell array to store the tables
for index = 1 : numIters
t0 = table();
tables{index} = t0;
end

Try this.
t1 = table();
t1.Name = 'My Name';
t1.Age = 89;
data = table();
data.Name = 'Your Name';
data.Age = 15;
% Append data contained in the t1 table to the data table
data = vertcat(data,t1);

Thanks for your answer Elias.
This approach shows how to store results from a for loop in one table if I understand correctly.
However, my problem is that I want each iteration to store its results in separate tables. I.e. if the for loop has 3 iterations, there should be three output tables, etc.

the statement "data = vertcat(data,t1); produced and error. Could not concatenate the table variable 'Name' using VERTCAT.
Caused by: Error using vertcat Dimensions of arrays being concatenated are not consistent.

Hi!
This thread is being very useful but I cannot find the way to save my tables in a excel file.
Here is the code
for jj = 1 : length(theFiles)
Table_parameters_spike = table(T,Q_spike,I_max,AT_HW,AT_RT)
filename = sprintf( 'Spike_%d', jj );
writetable(Table_parameters_spike, filename)
end
I got 5 .txt files but my objective is to get 1 .xls file with all the tables (2x5) concatenate vertically
Thanks!
