            dom: 'B<"pull-right"f>rtip',
            buttons: [
                {   extend: 'selected',
                    text: 'Agregar parcela',
                    action: function ( e, dt, node, config ) {
                      alert(dt.row().data()[8]);

            ],
            columnDefs: [ {
                orderable: false,
                className: 'select-checkbox',
                targets:   0
            },
                {

                targets: [8],
                visible: false,
                searchable: false
            }
            ],
            select: {
                style:    'os',
                selector: 'td:first-child'
            },
            order: [[ 1, 'asc' ]]
        } );

} );
