angular2-nativescript

问题 I am busy with a very basic Angular2/Nativescript app where i'm trying to replicate a table from a web app where I display stock transactions using Nativescript's GridLayout and ListView... i'm not sure there's a way to add all content in the ListView and not have the table headers repeat with in every item in the ListView so i've created two GridLayouts, one at the top and one contained in the ListView... When I click on the show stock transactions button the ListView doesn't show at all.
