for j=1:2
tCOD{j,:}=readtable(full_file_name(j,:),'FileType','text', 'headerlines',end_of_header_line(j),'readvariablenames',0); % 2x1 cell
end
data_1=tCOD{1,:} ; data_1=data_1{:,3:8}; % nx6 table
data_2=tCOD{2,:} ; data_2=data_2{:,3:8}; % nx6 table
How can I merge data_1 and data_2 as a single variable within the above loop?

If you've read two "similar" tables into a 2x1 cell array, best ting to do is to vertvat them outside the loop:
>> C = {array2table(rand(4,3)) array2table(rand(5,3))}
C =
1×2 cell array
{4×3 table} {5×3 table}
>> t = vertcat(C{:})
t =
9×3 table
Var1 Var2 Var3

You can vertcat incrementally inside the loop, but this is faster.
This
data_2=data_2{:,3:8}; % nx6 table
doesn't create a table, it extracts data from a table. You may not be intending to do that.
