  Hi Richard,

  What you need to do is store the options.level array in a variable scoped so that the rendering function can see it via the xhr event:

  let levelOptions = [];
  let table = $('#myTable')
    .on('xhr', function (e, s, json) {
      levelOptions = json.options.level;
    })
    .DataTable({
      columns: [{
        data: 'level',
        render: function (data) {
          // lookup in `levelOptions`
        }
      }]
    });
  

  You might want to convert the label / value array into a Map, keyed by the value, so you can do a quick lookup on it.

  Hmm..odd....when I place a console.log inside the xhr Event it is not triggered at all:

      let levels = [];
      let table = $('#kommunikation')
        .on('xhr', function (e, s, json) {
          levels = json.options.pegel;
          console.log(json);
        })
        .DataTable({
  

  Thought there would be already a built-in options to access the options as with the file array used for rendering images.

  Is that something worth to implement in the future?
  Most columns use a foreign key who's label/values are accessible via the editor's select fields.

  Ah found it...should be:

      let table = $('#kommunikation')
        .on('xhr.dt', function (e, s, json) {

  Just for reference for others maybe (o;

  Looks like this now:

      var levels;
      let table = $('#kommunikation')
        .on('xhr.dt', function (e, s, json) {
          levels = new Map(json.options.pegel.map((obj) => [obj.value, obj.label]));
        })
        .DataTable({
  

  and the render part:

              { data: "level", className: 'editable dt-body-left',
                render: function(data, type) {
                  if(type = 'display')
                    return levels.get(data);
                  return data;
                }
              },

  Oops - you are right. I'm so used to using DataTables' on() method which added that namespace automatically!
