How to stop loop rewriting

I have this loop but it only shows results for the final iteration. I have 10 files and want to see results for all 10 files. Any ideas?

notebook = readtable('notebook.xlsx');
filename = notebook.Filename; 
num_files = length(filename); 
exp = cell(1,num_files);
set(0,'DefaultFigureWindowStyle','docked')
for n = 1:num_files
    fname = filename{n};
    exp{n} = import_wcp(fname);
    num_samp = size(exp{n}.S{1},1);
    t = 0:exp{n}.t_interval:(num_samp-1)*exp{n}.t_interval;
    B = exp{n}.S{1,1}(1:400,:);
    B(B>-0.1) = [0];
    B(B<-0.6) = [0];
end

notebook = readtable('notebook.xlsx');
filename = notebook.Filename; 
num_files = length(filename); 
exp = cell(1,num_files);
set(0,'DefaultFigureWindowStyle','docked')
T = cell(num_files,1) ; 
BB = cell(num_files,1) ; 
for n = 1:num_files
    fname = filename{n};
    exp{n} = import_wcp(fname);
    num_samp = size(exp{n}.S{1},1);
    t = 0:exp{n}.t_interval:(num_samp-1)*exp{n}.t_interval;
    B = exp{n}.S{1,1}(1:400,:);
    B(B>-0.1) = [0];
    B(B<-0.6) = [0];
    % Save each file t, B 
    T{n} = t ;
    BB{n} = B ; 
end
celldisp(T)
celldisp(BB)

If the data size in each cell is same, you can save them into a matrix by initializing matrix instead of cell array or convert the cell array into matrix using Cell2mat.
