如何在ruby on rails的datatable中添加多选？

<%= form_tag(action: 'batch_action', method: 'post') do %>
  <table id="datatable">
    <thead>
      <tr>
        <th><input type="checkbox" id="select-all"></th>
        <th>Name</th>
        <th>Email</th>
        <!-- 其他列 -->
      </tr>
    </thead>
    <tbody>
      <% @users.each do |user| %>
        <tr>
          <td><input type="checkbox" name="selected_ids[]" value="<%= user.id %>"></td>
          <td><%= user.name %></td>
          <td><%= user.email %></td>
          <!-- 其他列 -->
        </tr>
      <% end %>
    </tbody>
  </table>
  <%= submit_tag('Batch Action') %>
<% end %>

def batch_action
  selected_ids = params[:selected_ids]
  # 执行批量操作，例如删除选中的数据行
  User.where(id: selected_ids).destroy_all
  redirect_to users_path, notice: 'Batch action completed.'
end
