Answer 1

Use page.info() API method to get paging information about the table.

It returns an object, for example:

{
    "page": 1,
    "pages": 6,
    "start": 10,
    "end": 20,
    "length": 10,
    "recordsTotal": 57,
    "recordsDisplay": 57
}

Usage:

function getNumFilteredRows(id){
   var info = $(id).DataTable().page.info();
   return info.recordsDisplay;
}
