Can someone help me with an operation for adding two columns of a table together?

I feel that this should be a fairly simple code, but I seem to be having problems. I have a table with 2 columns. Each column has 64 points. I need to add point 1 from column 1 to point 1 from column 2, then point 2 in column 1 to point 2 in column 2, all the way to point 64. I would like to do this with out having to add each one individually, so I was wondering if anyone had an operation to do this. I also would like to display the results in the third column of the table just for an easy way to compare all the points.
Thank you for your help!
Suppose the names of the waves in the columns are wave0 and wave1. Also suppose that you are in the data folder where those waves are located.

duplicate/O wave0, sumwave
sumwave = wave0 + wave1
appendtotable sumwave
display sumwave
