And the code of the table(inside template node):

<script type="text/javascript" src="/tabulator-tables/dist/js/tabulator.min.js"></script>
<link rel="stylesheet" href="/tabulator-tables/dist/css/tabulator_semanticui.min.css" />
<div id="table-messungen"></div>
<script>
    var tableM = new Tabulator("#table-messungen", {
        height:"1000px",
        placeholder:"Keine Daten verfügbar!",
        layout:"fitColumns",
        pagination:true,
        paginationMode:"remote",
        //groupBy:"Zeitstempel",
        //groupToggleElement:"header",
        ajaxURL:"http://10.207.48.36:1880/fetchmessungen",
        paginationSize:1000,
    /*
        initialSort:[
            {column:"Zeitstempel", dir:"asc"},
        ],
    */
        columns:[
            {title:"Register", field:"Register", width:150},
            {title:"Druck (Pascal)", field:"Druck"},
            {title:"Zeitstempel", field:"Zeitstempel"},
        ],
       
    });
</script>
