Question

我正在使用数据表来显示正在运行的列表。现在默认过滤器我得到Show entries和search。

我必须为过滤器添加一个下拉列表，称为role。如果用户选择“领导者”，那么它将填充记录并显示在列表中。还有

如何在顶部显示两个以上的下拉菜单，而不显示底部？

您能帮我吗？

var Table = $('#list').DataTable();

.e_list {
  width: 80%;
  margin: auto;
  text-align: center;
}

  <div class="pad0 m_b_20">
    <div class="e_list">
      <table cellspacing="0" id="list">
        <thead>
          <tr>
            <th>Sr.no</th>
            <th> Employee Name </th>
            <th> Mobile No. </th>
            <th> Designation </th>
            <th> Role </th>
            <th> Status </th>
          </tr>
        </thead>

我从数据表的官方文档中获得了代码

如何在数据表中显示多个过滤器下拉菜单？
