Accessing page table data in the widget

I have a page with implements HasTable and I need the widget to be related to the table data.

I have tried this option in the Panel Builder, but it doesn't work for me:
https://filamentphp.com/docs/3.x/panels/resources/widgets#accessing-page-table-data-in-the-widget

It gives me this error:
Property [$activeTab] not found on component: [app.filament.pages.report]

In the view I only have this
<x-filament-panels::page>
    {{ $this->table }}
</x-filament-panels::page>
Was this page helpful?
