forEach处理List每行显示固定的几个 博客分类： Page

我用C标签中的forEach取值，如何每行显示4个，多的在第二行显示！
<c:forEach  var="s" list="${list}" varStates="vs">
  <c:if test="${vs.count%4==0}"><br></c:if>
</c:forEach>

 

以下是个实际的使用列子：（注意如果最后一行不是4个，就需要补充空的td，例子有处理，但需要传参数）

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>

<table width="100%" border="0" cellspacing="0" cellpadding="0" class="sxlist_tab" name="table" id="table">
  <thead>
    <tr>
          <th width="4%">序号</th>
          <th width="28%">事项类别</th>
          <th width="28%">项目名称</th>
          <th width="12%">提醒时间</th>
          <th width="28%">提醒内容</th>
    </tr>
  </thead>
  <tbody>
  <c:choose>
	<c:when test="${!empty effReceiveInstanceList}">
		<c:forEach items="${effReceiveInstanceList}" var="effBean" varStatus="status">
       <tr>
          <td>&nbsp;${effBean.indexnum }</td>
          <td title='${effBean.apply_item_name}'>
		   <c:choose>   
				<c:when test="${fn:length(effBean.apply_item_name) > 20}">   
					<c:out value="${fn:substring(effBean.apply_item_name, 0, 20)}..." />   
				</c:when>   
			   <c:otherwise>   
				  <c:out value="${effBean.apply_item_name}" />   
			   </c:otherwise>   
			</c:choose>
		  </td>
          <td title='${effBean.projectname }'>
			<c:choose>   
				<c:when test="${fn:length(effBean.projectname) > 20}">   
					<c:out value="${fn:substring(effBean.projectname, 0, 20)}..." />   
				</c:when>   
			   <c:otherwise>   
				  <c:out value="${effBean.projectname }" />   
			   </c:otherwise>   
			</c:choose> 
		  </td>
		  <td>&nbsp;${effBean.sentdate }</td>
          <td title='${effBean.news_content }'>
		  <c:choose>   
			<c:when test="${fn:length(effBean.news_content) > 20}">   
				<c:out value="${fn:substring(effBean.news_content, 0, 20)}..." />   
			</c:when>   
			<c:otherwise>   
			  <c:out value="${effBean.news_content }" />   
			</c:otherwise>   
		   </c:choose> 
		  </td>
    </tr>
		</c:forEach>
	</c:when>
</c:choose>
  </tbody>
