Add variables from one timetable to another

Having a bit of trouble with this...
I've got two timetables. Let's call them TT1 and TT2.
One table (TT1) has 11 variables. Another table (TT2) has 1035 variables. They are the same length.
I would like to take variables 12:1035 and move them to the right of the last variable in TT1.
What is the best approach?

Hi,
I think you could easily achieve that using outerjoin function. First, extract your data from TT2 and give it a name such as NewTable = TT2(12:1035). Then, use outerjoin function to merge them
FinalTable = outerjoin(TT1,NewTable).
Please see the documentation of this function and how to use it examples https://www.mathworks.com/help/matlab/ref/outerjoin.html
And if you find this helpful, make sure to accept the solution!
Thanks

Eric, I think all you need is
>> T1 = array2table(rand(5,3),"VariableNames",["A" "B" "C"]);
>> T2 = array2table(rand(5,3),"VariableNames",["X" "Y" "Z"]);
>> T12 = [T1 T2(:,["Y" "Z"])]
T12 =
5×5 table
A B C Y Z

You will need to make sure you don't have variable name conflicts.
The join functions are sort of a horz cat when you want to match up rows based on their values, not their positions. synchronize is sort of a horz cat whn you want to match up rows (of timetables) based on their times.
