Need to join 2 tables and keep all the columns from both the tables as output. The outer join need to happen

So i have 2 tables - Input1 and input2 as follows –>
Input1 is feeding into a loop and creating input 2. once the input2 is completed, i wan tot join input1 and input2 whihc i trying to via merge.
