mat-tableSıralamanın yerel olarak çalışmasını sağlamaya çalışıyorum ve verilerin beklendiği gibi gösterilmesini sağlayabilirken, başlık satırına tıklamak çevrimiçi örneklerde olduğu gibi sıralamayı yapmıyor (hiçbir şey olmuyor). Bu demoyu yerel olarak çalıştırmaya çalışıyorum:
https://material.angular.io/components/sort/overview

Angular CLI ile yeni bir proje oluşturdum, ardından şu adımları izledim: https://material.angular.io/guide/getting-started
İşte yerel dosyalarım:

Neden çevrimiçi tablo gibi görüneceği konusunda bir fikri olan ancak sıralama işlevselliğinden yoksun olan var mı?
ng test --sm=falseve ne çıkacağını gör.
