How to upload a file to a table using a modal and Jquery?

I have a dynamic table which allows a person to upload an image, their name and surname within a modal when they click a button. When I try upload the image my table displays "undefined" in the place of the image. How do I get the table to display the image?

I've tried using .val(), .attr('src'). I am new to jquery so I'm sure I'm making a rookie mistake here, but I'm out of ideas and can't seem to find a similar issue anywhere.

$(document).ready(function () {
    $("#save_btn").click(function () {
        let image = $("#Image").attr('');
        let name = $("#Name").val();
        let surname = $("#Surname").val();
        $('#myTable').append(
            '<tr>' +
            '<td>' + image + '</td>' +
            '<td>' + name + '</td>' +
            '<td>' + surname + '</td>' +
            '<td> <button id="edit" class="btn btn-sm material-icons" style="color: green"> create </button> </td>' +
            '<td><button id="delete" class="btn btn-sm material-icons" style="color: red">delete</button></td>' +
            '</tr>'
        );
    });
    
    });

I made a change to the append function. I added this...

"<td>" + "<img id='table_image' alt='' src='" + './images/' + image + "' > " + "</td>" +

$(document).ready(function () {

     $('input[type="file"]').change(function(e){
               fileName=URL.createObjectURL(e.target.files[0]);
            });
        $("#save_btn").click(function () {
            //let image = $("#Image").attr('src',fileName);
            let name = $("#Name").val();

You are assigning blank attr value. Please see updated code as below.

$(document).ready(function() {
  $("#save_btn").click(function() {   
    var fileNameIndex = $("#Image").val().lastIndexOf("\\") + 1;
    var image = $("#Image").val().substr(fileNameIndex);    
    let name = $("#Name").val();
    let surname = $("#Surname").val();
    $('#myTable').append(
      '<tr>' +
      '<td>' + image + '</td>' +
      '<td>' + name + '</td>' +
      '<td>' + surname + '</td>' +
      '<td> <button id="edit" class="btn btn-sm material-icons" style="color: green"> create </button> </td>' +
      '<td><button id="delete" class="btn btn-sm material-icons" style="color: red">delete</button></td>' +
      '</tr>'
    );
  });
