About Package Code:

@Input: The @Input() decorator in a child component or directive signifies that the property can receive its value from its parent component. For now our parent component can be app component and child component can be package.

@viewChild: Property decorator that configures a view query. The change detector looks for the first element or the directive matching the selector in the view DOM. If the view DOM changes, and a new child matches the selector, the property is updated. In this package i used viewChild to paginator and sorting so that anything that is changing meaning that user click on incearsing of page in pagination or on clicking sorting that change can be updated. ngAfterview: Respond after Angular initializes the component's views and child views, or the view that contains the directive. To initialize my paginator and sorting i used afterview decorator.

ngOnnit: Initialize the directive or component after Angular first displays the data-bound properties and sets the directive or component's input properties.

get field(): this function will return field names meaning from headerName data. which we will use in HTML <tr mat-header-row *matHeaderRowDef="field">

addData(): here we initiate data value from incoming data from app to table data.

isEmpty: this function is used to check whether is there filter value is selected or not if there is filter then this function will return boole value;
