🤨 Rationale

The nimble-table doesn't support being configured with height: auto, so this styling should be removed from the example app. With height: auto, no rows of the table are rendered in the app. See #1624

👩‍💻 Implementation

Remove height: auto from the example app's styling. Now the table uses the default height set in the nimble-table's :host styling. This is aligned with how the Blazor example app is styled.

🧪 Testing

• Verified the rows of the table are now rendered in the Angular example app
