struts2的jsp页面的table每行显示四个td应该怎么写代码？

Question

我在某table里用<s:iterator>显示某List的内容，想每行显示四个td，写了如下代码：

<s:if test="!(#st.index % 4)"><tr></s:if>

某些td代码

<s:if test="!(#st.index % 4)"></tr></s:if>

结果显示错乱，有的行显示一个td，有的显示3个。怎么才能按照我的想法显示？

Answer 1

问题解决了，应该在<s:iterator>和</s:iterator>标签之间放入：&nbsp; &nbsp; &nbsp; &nbsp; <s:if test="(#st.index % 4) == 0 && (#st.index != 0)">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </tr>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; </s:if>&nbsp; &nbsp; &nbsp; &nbsp; <s:elseif test="#st.index == 0">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; </s:elseif>

Answer 2

这样不行吗<s:iterator value="#list" id="obj">&nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; <td></td>&nbsp; &nbsp; &nbsp; &nbsp; <td></td>&nbsp; &nbsp; &nbsp; &nbsp; <td></td>&nbsp; &nbsp; &nbsp; &nbsp; <td></td>&nbsp; &nbsp; </tr></s:iterator>

Answer 3

<s:iterator>&nbsp; &nbsp; &nbsp; &nbsp; <s:if test="(#st.index % 4) == 0 && (#st.index != 0)">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </tr>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; </s:if>&nbsp; &nbsp; &nbsp; &nbsp; <s:elseif test="#st.index == 0">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tr>&nbsp; &nbsp; &nbsp; &nbsp; </s:elseif></s:iterator>
