There is no way to access the internal variables of a function from outside
that function. Do you specifically need a count of the rows in the
DataTable or would a count of rows in the HTML table suffice? If the
latter is goo enough, then you can use this to get the count of rows:
var rowCount = document.querySelectorAll('#myTable tr').length - 1; //
subtract 1 since the first row is a header
where "myTable" is the id of the table's container div.
