Hi,
I have a table with 3 columns but many rows. Some rows are the same on column 1 and 2 but but not on column 3. Since column 3 are numbers, how to collapse the table with rows that have the same col 1 and col2 and average on col 3?
For example, the table is
Symbol Date PriceNFLX 7/28/2015 100NFLX 7/28/2015 101AAPL 7/28/2015 150
I would like to make it as two rows:
NFLX 7/28/2015 105AAPL 7/28/2015 150
How to do that?
Thanks for any help!
Jennifer
