Pagination: Add getTotalRecords and getCurrentPageRecordsTotal

Hello,

This is my first post

So as we are not getting the total records and current page records in pager library to the template from pagerRenderer.php
I can workaround for total records by adding this to pagerRenderer.php :

Code:

public function getTotalRecordsCount(): int
    {
        return $this->total;
    }

but for current page records count i didn't found any solution
 
please add them so we can show bottom of the table the counts of records 

I also want to ask if there is way list S.No. (numbers) like we do within foreach loop as $i=1 and in the $i++;
sorry if there is already a solution
