You can define date format in date pipe https://angular.io/api/common/DatePipe

<table mat-table [dataSource]="dataSource" matSort class="mat-elevation-z8">
        <ng-container matColumnDef="name">
            <th mat-header-cell *matHeaderCellDef mat-sort-header>Name </th>
            <td mat-cell *matCellDef="let element" [attr.title]="element.name">{{element.name}}</td>
        </ng-container>
        <ng-container matColumnDef="date">
            <th mat-header-cell *matHeaderCellDef mat-sort-header>Date </th>
            <td mat-cell *matCellDef="let element" [attr.title]="element.date">{{element.date | date:'MMM d'}}</td>
        </ng-container>
</table>

To filter out by date you do something like

<ng-container *ngIf="element.date | date:'MMM d' === 'Nov 10'"><ng-container>

setting the custom filterPredicate method helps you to solve this issue, please refer the stackblitz link mentioned below

my response is to use the bests practice and call the data filter in the http call pass the data like a parameters es:

http://your-call?data=....

but if you don't want to do it i suggest you tu use a local variable in the .ts file like :

html:

//in the stamp of row of your table 
<div *ngIf="element.data==local-data">

in the ts:

local-data;
passData(data){
this.local-data=data;
}
