I want a column that sums the metrics I included in my table. Can I add the total of two Explore table columns?
Yes, you can create a standard calculated metric to add a column that shows the sum of your numbered metrics and or attributes. You can also create a result metric calculations that show the same result.
For example, to show the sum of your Inbound calls and Outbound calls metrics, you can create a calculated metric that looks like the image below.
This adds a new metric that you can include in your query to show the sum in columns.
For more information on how to add totals to your rows, see the article: Adding totals to results.
