Try:
% Random data to work with
DMax = [1 2 3 4 5]';
DMin = [0.1 0.2 0.3 0.4 0.5]';
DMaxInk = [11 22 33 44]';
DMinInk = [0.11 0.22 0.33 0.44]';
% Create table and create columns DMax and DMin
T = table;
T.DMax = DMax;
T.DMin = DMin;
If this is just one-time thing and you do not wish to automate this process, you can match the lengths by adding empty values.
% Adding NaN values on the end
DMaxInk(end+1,1) = NaN;
DMinInk(end+1,1) = NaN;
% Create columns for DMaxInk and DMinInk
T.DMaxInk = DMaxInk;
T.DMinInk = DMinInk
% Save the table
writetable(T,"your_table_name.xlsx");
