如何在JSP页面中动态创建表的行和列

试试这个代码：

<table width="59%" border="1">    <%        MySql1 o = new MySql1();        o.connect();        ResultSet r;        int counter=1;        String q = "select * from category_master;";        r = o.getdata(q);        ResultSetmetaData metaData = r.getmetaData();        while(r.next())        { %>     <tr>      <%      for(int i = 1; i<=metaData.getColumnCount();i++)         { %>          <td>          <%= r.getString(i)%>          </td>     <%          }     %>  </tr> <%         }    %></table>
