How to use Radio group into data table on multiple row? When I click on radio button from second row it changed on first row.

  <td
                            *ngIf="i+1 >= mdbTablePagination.firstItemIndex && i < mdbTablePagination.lastItemIndex">
                            <span class="form-check">
                                <input type="radio" mdbInput class="form-check-input" id="materialUnchecked"
                                    name="materialExampleRadios" [(ngModel)]="el.swiftStatus" [value]="el.swiftStatus" 
                                    (click)="outgoingAuthorizaionMessageModify(el.documentNo)">
                                <label class="form-check-label" for="materialUnchecked"></label>
                            </span>

                        </td>
                        <td
                            *ngIf="i+1 >= mdbTablePagination.firstItemIndex && i < mdbTablePagination.lastItemIndex">
                            <span class="form-check">
                                <input type="radio" class="form-check-input" id="materialChecked"
                                    name="materialExampleRadios" mdbInput [(ngModel)]="el.swiftStatus" [value]="el.swiftStatus"
                                    (click)="outgoingAuthorizaionMessageApprove(el.messageType, el.documentNo)">
                                <label class="form-check-label" for="materialChecked"></label>
                            </span>                                
                        </td>
