jQuery DataTables “No Data Available in Table” and tabled folds when sorting

问题

I have this error now too as per this post ”. and have modified code as per the post, but still getting the "no data Available in Table. In addition, I have added Sort buttons, however, when click the table rolls up and there is no way to un roll it. Not sure why this is not working. Thanks in advance

my jquery functions is

$(function () {
        $.ajax({
          method: "GET",
          url: URL  + '/rents/' + getParameterByName('id') ,
          dataType: "json",
          cache: false,

          })
            .done(function (data) {
         rentResponse = data.rent
         $.each(rentResponse, function(i, item) {

             if (item.activeEntry) {
               var $tr = $('<tr>').append(
                 $('<td>').text(moment(item.datePaid).format ('DD-MMM-YYYY')),
                 $('<td>').text(item.paymentType),
                 $('<td>').text('$'+item.amountPaid),
                 $('<td>').text('$0.00')
              ).appendTo('#datatable tbody')}
         })
          $('#datatable').DataTable();
        })
            .fail(function( xhr, status, errorThrown ) {

                console.log( "Error: " + errorThrown );
                console.log( "Status: " + status );
                console.dir( xhr );
            })
   })

and the HTML is

<table id="datatable" class="table table-striped table-bordered">
    <thead>
      <tr>
       <th>Date</th>
       <th>Payment</th>
       <th>Amount</th>
       <th>Balance</th>
      </tr>
     </thead>
      <tbody>

      </tbody>
   </table>

this is the JSON I m working with

  "rent": [
    {
      "_id": "5895a925cf8fd70011ceb6ab",
      "tenantID": "589416dd63998500117d9281",

    }
  ]

table when sort buttons pressed

The issue is that you're trying to do too much with your ajax. You could use something like this:

let datatable = $("#datatable").DataTable({
  "ajax": {
    "type": "POST",
    "url": "/echo/json/",
    "dataType": "json",
    "dataSrc": "rent",
    "data": {
      "json": JSON.stringify(jsonData)
    }
  },
  "columns": [{
    "title": "Date",
    "data": "datePaid",
    "render": function(d) {
      return moment(d).format("DD-MMM-YYYY")
    }
  }, {
    "title": "Payment",
    "data": "paymentType"
  }, {
    "title": "Amount",
    "data": "amountPaid",
    "render": function(d) {
      return "$" + d
    }
  }, {
    "title": "Balance",
    "render": function() {
      return "$0.00"
    }
  }]
});

Which lets DataTables do its own thing and KNOW about the data.
