MatPaginator not working properly on deleting rows

问题:

I have created a table with selection and pagination in angular 2 using angular material.

I have taken a button with the name Remove Selected Rows to delete the selected rows from the table.

But as a delete the selected rows , all the table data is being loaded which doesn't match with value specified for the pagination.

Below is the stack-blitz link for my code..

https://stackblitz.com/edit/delete-rows-mat-table-vj4hbg?file=app%2Ftable-selection-example.html

Below shown is the output.

Initially the table displays only the rows as specified for the pagination value.

But as I deleted the row 3 , all rows are being loaded even if the pagination value is only 3..

can anybody tell me how can I limit my table rows with the pagination value specified after deleting the rows.

Here you go buddy.

You forgot to reassign the paginator to the datasource after deletion. Angular may do some magic, but sometimes it needs a little bit of help.

I use a timeout because I always face an issue, feel free to try without it.

setTimeout(() => {
  this.dataSource.paginator = this.paginator;
});
