How can I add a total (sum) at the bottom of this table? I would like to sum the vines and Acerage columns. Using Arcmap.

Answer: 
I'm assuming that you're using ArcMap. The attribute table is not Excel. It doesn't have the ability to summarise data. You could do one of the following:

1. Manually create another row or text element and populate the data.
2. Export the data to Excel and run the sums there. Then copy and paste the table back into ArcMap.
You could also export the attribute table to a .dbase file and **then click** **and drag** that file into Excel. If you try to use open sometimes it doesn't work.
