"How do I merge the data to have them both in one table?"
It depends on how what's in the array corresponds to what's in the table.
If: (1) the table has the same number of variables as the array has columns, and (2) all variables in the table are column vectors, and (3) you want to add the array to the end of the table, and (4) each variable in the table should match with the corresponding column of the array (i.e., they're in the same order), then it's pretty easy to do:
one_table = table([1;2;3],[4;5;6],[7;8;9])
separate_array = 10*magic(3)
separate_table = array2table(separate_array,'VariableNames',one_table.Properties.VariableNames);
final_table = [one_table; separate_table]
But I had to make 4 assumptions about the situation and your objective. If any of those assumptions are incorrect, then you'll have to do something else. The actual situation may be almost as easy to deal with as this simple case, or it may be much more difficult or impossible to achieve your objective.
