Answer 2

代码结构有点问题，我稍微改了一下：
<%@ page contentType="text/html;charset=gb2312" import="java.sql.*" import="java.util.*"%>
<jsp:useBean id="db" scope="page" class="DbConnect.util.mysqlDB_cmb_image" /><%
    String sql ="",sql2="";
    ResultSet rs = null;
    ResultSet rs2 = null;
    String id,idPrimal,pinpai,smallUrl,type,banquan="";
%>
<%
    sql = "select count(*) from image";
    rs = null;
    rs = db.executeQuery(sql);
    rs.next(); 
    int allCount = rs.getInt(1); 
    rs.close();
    db.closelink();
%>
<%
    sql = "select * from image";
    rs = db.executeQuery(sql);
%>
<table border="1">
<%
    int cols=4;//自己定义列数
    for(int i=0;i<allCount;i+=cols)
    {
        out.print("<tr>");
        for(int j=0;j<cols;j++)
        {
            out.print("<td valign='bottom'>");
            try
            {
                if(!rs.next()) throw new Exception("1");
                id = rs.getString("id");  
                idPrimal = rs.getString("idPrimal");  
                pinpai = rs.getString("pinpai");
                type = rs.getString("type");
                smallUrl = rs.getString("smallUrl"); 
                sql2 = "select banquan from pinpai";
                rs2 = null;
                rs2 = db.executeQuery(sql2);
                rs2.next(); 
                banquan = (String)rs2.getString("banquan");
                db.closelink(); 
                //我把这里的td移到上面了
                out.print("<table align='center'>"); 
                //图片
                //这里是你原来的代码，省略...
                out.print("</div>");
                out.print("</td></tr></table>");
                out.print("</td></tr>");
                out.print("</table>");
            }  
            
            catch(Exception e)
            {
                if(e.getMessage().equals("1")){
                    out.println("&#160;");//多余的<td>填充空格
                }
                else{
                    System.out.println("其他类型的错误,自己再处理一下");
                }
            }
            out.print("</td>");
        }
        out.print("</tr>");
    }
    rs.close();
    db.closelink();
%>
</table>
