I have been following the online Zen Quickstart Tutorial using the lastest release documentation. In addition to playing around with the styling and making a few minor functionality tweaks, I wanted to add an additional column that shows a count of the number of phone numbers for that Contact (as shown in the image below).
The idea here is that you can see what contacts have phone numbers without having to click on the "view phones" link. All I have done here is add a blank additional column to the %ZEN.Component.tablePane object
