分頁不起作用

Question

我在我的代碼中遇到了一個問題，那就是表分頁不起作用。可能只有5條記錄被檢索。請幫我解決我的問題：

它只是現在顯示在表

<form name ="form" action="Report1.jsp" method="post" > 
<%! int numPages = 0; %> 
<% 
String columnName = ""; 
int count = 0; 
int totalCols = 0; 
int increment = 1; 
int numRows = 0; 


String startIndexString = request.getParameter("startIndex"); 

if(startIndexString == null) { 
startIndexString = "1"; 
} 

int startIndex = Integer.parseInt(startIndexString); 

try{ 

totalCols = 1; 
%>

乍一看我的SQL的第一條記錄，你可以只打印一行becouse你totalCols爲1和J for cxan只能小於或等於totalCols。

totalCols = 1; 
%> 
    <table border="1" width="84%" align="center" bgcolor=#66CCFF bordercolor=#000000 height="137"> 

     <tr> 
     <div id="container"> 
      <td colspan="7" height="65"> 
      <p align="center"><b>Customer Information Request Form</b></td> 
     </tr> 
       <tr> 
      <td colspan="2" height="33"> 
      <p align="center"> 
      <span style="font-size: 8pt; font-weight:700">CIR_ID</span></td> 
      <td height="33"> 
      <span style="font-size: 8pt; font-weight:700">Bank Name</span></td> 
      <td height="33" width="26%"> 
      <span style="font-size: 8pt; font-weight: 700">Request From</span></td> 
      <td height="33" width="18%" colspan="3"> 
      <span style="font-weight: 700; font-size: 8pt">Created</span><span style="font-size: 8pt; font-weight: 700"> 
      Date</span></td> 
     </tr> 
<% 
for(int j=1; j<=totalCols && rs.next(); j++) {
