I want to get the data datum_bis in my console. But how does it works?

    var table = $('#example').DataTable( {   
        
//         "createRow": function ( row,data,index){
//             if ( data[2] <= '10.10.2020' ) {
//                 $('td', row).eq(2).addClass('highlight');
//             }
//         },
        order: [[ 2, 'desc' ],[ 1, 'asc' ]],
        columnDefs: [
            { type: 'de_date', targets: [1,2] }             //Datum Sortieren
        ],
    
        dom: "Bfrtip",
//         lengthChange: false,
        ajax: "staff.php",
        fixedHeader: {
            
            header: true,
            footer: true,
            headerOffset: 63
        },
        
        paging:         false,
        
        stateSave: true,                //zum speichern der anzuzeigenden Reihen
        
        columns: [
//          Textanzeige Tabelle   
            { data: null, render: function ( data, type, row ) {
                // Combine the first and last names into a single table field
                return data.p.vorname+' '+data.p.nachname;
            } },
            { data: "weristwo.datum_von", width: "20%" },
            { data: "weristwo.datum_bis", width: "20%" },
            { data: "a.abwesenheitsgrund", width: "20%" },

        ],
        select: true,
        //Button Farbe
        buttons: {
            className: "btn-light",             
             buttons: [
        
            //Neu and Cancel Button
            { extend: 'create', className: 'btn-light', text: 'Neu', editor: editor,
                formButtons: [
                    'Neu',
                    { text: 'Cancel', action: function () { this.close(); } }
                ] 
            },  
            
            //Edit Button + Funktion für vor, zurück und speichern
            { extend: 'selected',className: 'btn-light', text: 'Bearbeiten',editor: editor,
            action: function () {      
                    var indexes = table.rows( {selected: true} ).indexes();                    
                    editor.edit( indexes, {
                        title: 'Bearbeiten',
                        submitOnReturn: false,
                        buttons: indexes.length === 1 ?
                            backNext :
                            'Save',

                    } );
                        
                }, 
            },
        //Delete and Cancel Button
            { extend: 'remove', className: 'btn-light', text: 'Löschen', editor: editor,
            formMessage: function ( e, dt ) {
                    var rows = dt.rows( e.modifier() ).data().pluck('bez');
                    return 'Sicher das du folgende Einträge löschen möchtest? '
            },
            formButtons: [
                    { text: 'Abbrechen', action: function () { this.close(); } },
                        'Löschen'
            ]},
        ]},
        createdRow: function(row, data, type, name ) {
                console.log(HERE I WANT THE DATA OF DATUM_BIS);
//             }
        },
