Data between 2 diferent windows

I want to open a GUI window asking how many lines would the person like to work with, and after that another window (a table one) would appear with an editable (x,4) matrice. How can I do that?

% Ask for the number of rows

out = inputdlg('How many rows?');

% You should fill the uitable no matter what (I chose zeros)

dat = zeros(str2double(out{1}),4);

% Create uitable (up to you all the other settings)

t = uitable('data',dat,'ColumnEditable',true(1,4));
