如何从数据库中动态分配表头值

Question

我正在使用jsp，但是我无法直接从数据库动态分配表头。我尝试使用while条件，并直接从数据库中成功地将数据添加到多行中，但这在表头中没有发生。

这是我的代码：我想使其动态化，这样我就不必在所有页面中单独定义表头。

Class.forName("com.mysql.jdbc.Driver");
Connection con=DriverManager.getConnection("jdbc:mysql://localhost/price_list","root","root");
PreparedStatement ps=con.prepareStatement(""+query+"");
ResultSet rs=ps.executeQuery();

    <thead>
      <tr>
        <th data-field="Month">Month</th>
        <th data-field="CAR">CAR</th>
        <th data-field="Type">Type</th>
        <th data-field="Model">Model</th>
        <th data-field="GST EXSHOWROOM CHARGES">GST EXSHOWROOM CHARGES</th>
