No data available in first line of data table

After getting the data from firebase, the first line in the datatable is showing no data available. How should I correct this?

I know I'm only using one data set but I try with 10 data it's still showing that there is no data available in the first line.

I tried everything I know but nothing works.

Output

My js code

    $(document).ready(function() {      $('#user_data').DataTable({          dom: 'Bfrtip',            colums: [              { title: "USN" }, { title: "Email" }, { title: "Name" }, { title: "Password" }          ],          targets: -1,          className: 'dt-body-right',          hover: 1,        });   });   var rootRef = firebase.database().ref().child("StudentID");     rootRef.on("child_added", snap => {            USN = snap.child("UserUSN").val();      Email = snap.child("Useremail").val();      Name = snap.child("Username").val();      Password = snap.child("Userpassword").val();            $("#table-body-pengguna").append("<tr><td>" + USN + "</td><td>" + Email +            "</td><td>" + Name + "</td><td>" + Password + "</td></tr>");   })   

My html code

    <body>      <table id="user_data" class="display" width="100%" cellspacing="0">          <thead>              <tr>                 <th>USN</th>                 <th>Email</th>                 <th>Name</th>                 <th>Password</th>             </tr>          </thead>            <tbody id="table-body-pengguna">            </tbody>         </table>
