Greetings guys. I’m trying to use the Table of Primeng, but I’m struggling. I followed the steps in Get Started and the Table does not appear in the browser. And to make matters worse, there is no error in the browser console or code.

Your navigation pane Component.html shows some typos:

change:

<ng-template pTemplete="header">

for:

<ng-template pTemplate="header">

and:

<ng-template value="body" let-oportunidade>

for:

<ng-template pTemplate="body" let-oportunidade>
