angular - 如何在 MatTableDataSource 以外的地方使用 mat-paginator？

Question

我想要在 dataSource 下面的分页器，但它显示错误
属性 'paginator' 在类型 'MatTreeFlatDataSource<TreeNode, TreeFlatNode>' 上不存在

this.treeFlattener = new MatTreeFlattener(this.transformer, this.getLevel, this.isExpndable, this.getChildren);
this.treeControl = new FlatTreeControl<TreeFlatNode>(this.getLevel, this.isExpndable);

dataSource: MatTreeFlatDataSource<TreeNode, TreeFlatNode>;
this.dataSource = new MatTreeFlatDataSource(this.treeControl, this.treeFlattener);

尝试过

this.dataSource.paginator=this.paginator;
this.dataSource.data.paginator=this.paginator;
