[showFirstLastButtons]="paginatorShowFirstLastButtons"
[pageSizeOptions]="paginatorShowPageSizeOptions ? paginatorPageSizeOptions : []"
[hidePageSize]="paginatorHidePageSize"
[pageIndex]="paginatorPageIndex">
</mat-paginator>


::ng-deep .mat-select-panel .mat-option.mat-selected:not(.mat-option-multiple) {
