Angular MatPaginator not working

Question

I have 2 components. Both have mat-table and paginators and pagination is working for one component and not working for the other component though the code is similar. Below

Answer 1

I had the same issue (table data displaying but MatPaginator is not working). In my case, I forgot to create "new MatTableDataSource"

this.dataSource = somearray;

not enable MatPaginator while this.dataSource = new MatTableDataSource(somearray); does.

extract from material documentation

"To simplify the use case of having a table that can sort, paginate, and filter an array of data, the Angular Material library comes with a MatTableDataSource that has already implemented the logic of determining what rows should be rendered according to the current table state."

hope this answer helps someone.
