Make strings not appear in the same row

I’m trying to create an order form where multiple lines can be added and keep things clean. This issue is when I send it to my DB it combines the lines. I want each item to be on it’s own line.

For example, I want to have the teacher name, submitted by and notes show item1, description1, etc. The only things that should repeat would be the teacher, submitted and notes.

I’ve tried everything, but this is a little past my comfort zone!

My SQL Result

Note: it doesn’t seem to like the php’s, so it doesn’t show completely accurate.

$(document).ready(function() {

  jQuery($ => {
    let $table = $('#articles');
    var id = "id" + Math.random().toString(16).slice(2)
    var teachername = $("#txt_teachername").val();
    var submittedby = $("#txt_submittedby").val();
    var notes = $("#txt_notes").val();
    var item = $("#txt_item").val();
    var description = $("#txt_description").val();
    var quantity = $("#txt_quantity").val();
    var vendor = $("#txt_vendor").val();


    $table.on('input', '.teachername, .submittedby, .notes, .item, .description, .quantity, .vendor', function() {
      let $row = $(this).closest('tr');
      var teachername = $row.find('.teachername').val();
      var submittedby = $row.find('.submittedby').val();
      var notes = $row.find('.notes').val();
      var item = $row.find('.item').val();
      var description = $row.find('.description').val();
      var quantity = $row.find('quantity').val();
      var vendor = $row.find('.vendor').val();
    })

    $table.on('click', '.btn-remove', function() {
      if ($table.find('tr').length > 1) // prevent deletion of all rows
        $(this).closest('tr').remove();
