如何在jsp页面中从Mysql打印表？

Question

此Web项目要求我们实施一个电子商务网站。我试图在用户单击按钮后在jsp页面中打印由Mysql查询生成的表。我的小组负责人做了一些初步工作，但我不了解他使用的基础架构。似乎大多数东西都是在servlet中处理的。 在用户单击“打印销售报告”按钮后，我必须执行查询以生成销售报告表。 我该如何实施？

    String _token = (String) session.getAttribute("name");
    request.setAttribute("name", _token);
    boolean _isAdmin = (Boolean) session.getAttribute("e_type");
    request.setAttribute("isAdmin", _isAdmin);
