Hi,
I need to solve some issue that I stuck on. I want to add some rule that will check if specify column exists and if so add that one to another and give result in new named column. If the column doesn’t exist, create new named column anyway but give values from the second column.
So this is something to explain the issue. I need to check if column B exists and if so add A to B and give result in new named column “A+B”.
Desired result. I tried use Math formula as it has great option to name colum, but the problem is that when the colum B does not exist it gives error.
So in other words column A always exist but B does not.
I know that it can be done easly but I don’t know how. Maybe in simple java but I can’t write codes.
Thank guys for your help in advance.
