Get the right jquery datatable object on click event

I want to remove a row from a datatable table with an on click event. I got this based on the documentation and my code works. However I don't want to hard code the variable name for my datatable object in the remove function as there might be multiple or differently called datatables. How can I determine the correct object where the row should be removed?

Updated code in codepen https://codepen.io/bintux/pen/QWLKxQG based on @David Hedlund's answer.

var table = $('#example').DataTable();

$('.deleterow').on('click', function () {
    //I want to avoid this hard coded name for the datatable object but instead get the right object when the user clicks in the table    

    table
        .row($(this).parents('tr'))
        .remove()
        .draw();

});



var table = $('#example').DataTable();
$('.deleterow').on('click', function() {
  table
    .row($(this)
      .parents('tr'))
    .remove()
    .draw();
  //console.log(row);
});

.deleterow will always be a child of the table of interest.

Inside your click listener, you could access it like so:

var table = $(this).closest('table').DataTable();
