Answer 1

用<c:if test="">可以解决问题的

Answer 2

“预存数量”rowdata[6] 小于“库存数量” rowdata[8]
<table width="98%" border="0" align="center" cellpadding="1" cellspacing="1" class="tableStyle01">                     
      <tr>
      <td width="20%" align="center" nowrap class="TDstyle02"> <strong>教材名称 </strong> </td>               
      <td width="20%" align="center" nowrap class="TDstyle02"> <strong>出 版 社 </strong> </td>     
      <td width="10%" align="center" nowrap class="TDstyle02"> <strong>预存数量 </strong> </td>
      <td width="10%" align="center" nowrap class="TDstyle02"> <strong>库存数量 </strong> </td>
      <tr>
        <%
          for ( int i=0; i <jiaoCaiJiChuXinXiListdata.size(); i++ ) {
          String[] rowdata = (String[])jiaoCaiJiChuXinXiListdata.elementAt(i);  
String style = "";
int num1 = Integer.valueOf(rowdata[6]);
int num2 = Integer.valueOf(rowdata[8]);
if(num1 < num2){
    style = "color:red;weight:bold";
}                 
          %>                                                         
      <tr>
      <td height="30" align="center" class="TDstyle01"> <%= rowdata[1] %> </td>

      <%
          }
      %>

Answer 3

楼主用下面代码替换相应代码就可以：<%
    int number1 = 0;
    int number2 = 0;
    boolean isTrue = false;
    for ( int i=0; i <jiaoCaiJiChuXinXiListdata.size(); i++ ) { 
          String[] rowdata = (String[])jiaoCaiJiChuXinXiListdata.elementAt(i);
          number1 = Integer.parseInt(rowdata[6]);
          number2 = Integer.parseInt(rowdata[8]);
          isTrue = number1 < number2;
%>
<tr> 
      <td height="30" align="center" class="TDstyle01"> <%= rowdata[1] %> </td> 
      <td height="30" align="center" class="TDstyle01"> <%= rowdata[2] %> </td> 
      <td height="30" align="center" class="TDstyle01"> <%= rowdata[6] %> </td> 
      <td height="30" align="center" class="TDstyle01" <%if(isTrue)out.print("style=\"color:red;font-weight:bold\"")%>> <%= rowdata[8] %> </td>    
</tr>                                  
<% 
     } 
%>

<S:iteartor var="" id=""> 
 <tr>

 </tr> 
</S:iterator>

Answer 5

最好用标签，不要用<% %>嵌套代码。

Answer 7

好使了，感谢“boboo_2000_0”和“swandragon”，“swandragon”给的代码没有给“num1”赋初始值，出现错误；“boboo_2000_0”给的代码经过修改好使了，谢谢大家！
