Я использую таблицу компонентов материала, чтобы показать данные, и применил сортировку, фильтрацию и разбивку на страницы.Пользовательская фильтрация работает правильно, я перехожу по упомянутой ссылке https://v5.material.angular.io/components/table/overview#pagination, но застрял в пагинации ниже - мой код.Пожалуйста, помогите, где я сделал ошибку.

HTML-код 

<div class="example-container mat-elevation-z8">


  <div class="example-header">
    <mat-form-field>
      <input matInput type="text" (keyup)="applyComponent($event.target.value)" placeholder="Component" aria-label="Number" [matAutocomplete]="autocom">
    <mat-autocomplete #autocom="matAutocomplete">
      <mat-option *ngFor="let option of options" [value]="option">
        {{ option }}
      </mat-option>
    </mat-autocomplete>
    </mat-form-field>

    <mat-form-field class="mar-left">
      <input type="text" matInput aria-label="Number" (keyup)="applyRegion($event.target.value)" placeholder="Region" [matAutocomplete]="auto">
