刷新用循环填充的DataTables表

Question

我想更新表格内容而不刷新页面，但是我在同一页面上使用循环填充表格。这是我使用的代码：

<div id="items_table">
<div class="table-responsive" id="table_allitems">
<table id="products_all" class="table-sm table-bordered table-hover" style="width: 100%;">
<thead class="table-secondary table-hover">
  <tr>
    <th scope="col">
      <center>Код</center>
    </th>
    <th scope="col">
      <center>Име</center>
    </th>
    <th scope="col">
      <center>Баркод</center>
    </th>
    <th scope="col">
      <center>Група</center>
    </th>
    <th scope="col">
      <center>Мярка</center>
    </th>
    <th scope="col">
      <center>Количество</center>
    </th>
    <th scope="col">
      <center>Обект</center>
    </th>
    <th scope="col">
      <center>Доставна цена</center>
    </th>
    <th scope="col">
      <center>Продажна цена</center>
    </th>
    <th scope="col"></th>
  </tr>
</thead>
<tbody id="skladove_table">

 <?php
  $query_checkObekt = "SELECT * FROM obekti WHERE owner='$user_hash'";
  $result_checkObekt = mysqli_query($conn, $query_checkObekt);

  if(mysqli_num_rows($result_checkObekt) > 0) {

    $query = "SELECT * FROM items WHERE owner ='$user_hash'";
    $result=mysqli_query($conn, $query);

    while($row = mysqli_fetch_assoc($result))

            {
              echo '<tr id="' . $row['unique_id'] . '" onmouseover=showItem(' . $row['unique_id'] . ');>';

              echo "<td>" . "<center>" . $row['custom_id'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['name'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['barcode'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['grupa'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['quantity_type'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['quantity_number'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['obekt'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['price_delivery'] . "</center>" . "</td>";
              echo "<td>" . "<center>" . $row['price_sale'] . "</center>" . "</td>";
              echo "<td style='width: 1%; padding-left: 1%; padding-right: 1%;' onclick='deleteItem(" . $row['unique_id'] . ");'><i class='fa fa-close'></i>"."</td>";

              echo "</tr>";
            }

  } else {
    //no records found
  }

  ?>

  </tbody>
  </table>

要添加新项目，我使用iframe模态，而我想要的是在关闭模态后或仅按一个按钮表以刷新新信息（如果可能，请留在同一页面上）而不刷新页面。< / p>
