here is ts code

@ViewChild(MatSort) inventoryDataSort: MatSort;
@ViewChild(MatPaginator) inventoryDataPaginator: MatPaginator;

@ViewChild(MatSort) additionalDataSort: MatSort;
@ViewChild(MatPaginator) additionalDataPaginator: MatPaginator;
ngAfterViewInit() {
    this.inventoryDataSource.sort = this.inventoryDataSort;
    this.inventoryDataSource.paginator = this.inventoryDataPaginator;
    this.additionalDataSource.sort = this.additionalDataSort;
    this.additionalDataSource.paginator = this.additionalDataPaginator;
}

mat-table

<mat-table #table1 [dataSource]="inventoryDataSource" matSort>
<mat-table #table2 [dataSource]="additionalDataSource" matSort>

Answer 1

Selector in ViewChild queries DOM and it finds first math. Could you try change this part from

@ViewChild(MatSort) inventoryDataSort: MatSort;
@ViewChild(MatPaginator) inventoryDataPaginator: MatPaginator;

@ViewChild(MatSort) additionalDataSort: MatSort;
@ViewChild(MatPaginator) additionalDataPaginator: MatPaginator;

to

@ViewChild(MatSort) inventoryDataSort: MatSort;
@ViewChild(MatPaginator) inventoryDataPaginator: MatPaginator;

@ViewChild('table2', {read: MatSort}) additionalDataSort: MatSort;
@ViewChild('table2', {read: MatPaginator}) additionalDataPaginator: MatPaginator;
