When I run the script for one table, to visualize the table I just do like this (and it works fine):

% Create output variable

variables = table;

but when I'm reading multiple tables, how can I visualized the multiple tables read from a for loop in the variable space?

for i = 1:5

filename = sprintf('variables_%d.csv',i)

fileID(i) = fopen(filename,'r'); %check each file

dataArray = textscan(fileID(i), '%C%f%f%f%f%f%C%s%f%f%f%f%f%f%[^\n\r]', 'Delimiter', ',', 'TextType', 'string', 'HeaderLines', 1, 'ReturnOnError', false, 'EndOfLine', '\r\n');

fclose(fileID(i));

variables(i). = table();

end

I'm doing that but it is not working

Use cell array instead:

variables{i} = table(dataArray);

thank you, it is working I can not see like the whole table, but if I click each array then I see the values of each column

Create a cell array of tables:

for i = 1:5
    filename = sprintf('variables_%d.csv',i)
    fileID(i) = fopen(filename,'r'); %check each file
    dataArray = textscan(fileID(i), '%C%f%f%f%f%f%C%s%f%f%f%f%f%f%[^\n\r]', 'Delimiter', ',', 'TextType', 'string', 'HeaderLines', 1, 'ReturnOnError', false, 'EndOfLine', '\r\n');
    fclose(fileID(i));
    T{i} = table(dataArray);    % cell array of tables from the dataArray (modify this to create table)
end
% in workspace
T{2}
