如何强制表格单元格内容换行？

css

这是整个页面*可包装的内容在main.css文件中定义

/* Wrappable cell
* Add this class to make sure the text in a cell will wrap.
* By default, data_table tds do not wrap.
*/
td.wrappable,
table.data_table td.wrappable {
    white-space: normal;
}

这是整个页面：

<%@ include file="../../include/pre-header.html" %>
<form id="commentForm" name="commentForm" action="" method="post">



    <ctl:vertScroll height="300" headerStyleClass="data_table_scroll" bodyStyleClass="data_table_scroll" enabled="${user.scrollTables}">
        <ctl:sortableTblHdrSetup topTotal="false" href="show.whatif_edit_entry?   entryId=${entry.entryId}" />
        <table class="data_table vert_scroll_table">



            </tr>
            <tr>
                <ctl:sortableTblHdr styleClass="center" title="Comments" property="comment" type="top">Comments</ctl:sortableTblHdr>
            </tr>


            <c:forEach var="comments" items="${entry.comments}">


                <tr id="id${comments.id}">
                    <td id="comments-${comments.id}" class="wrappable" style="width:400px;">${comments.comment}</td>
                </tr>



            </c:forEach>
            <c:if test="${lock.locked || form.entryId < 0 }">
                <%-- This is the row for adding a new comment. --%>
                    <tr id="commentRow">
                        <td><input type="text" id="comment" name="comment" size="50" maxlength="250" onkeypress="javascript:return noenter();" />
                            <a href="javascript:addComment();"><img src="../images/icon_add.gif" border="0" alt="Add"/></a>
                        </td>

                    </tr>
            </c:if>

        </table>

    </ctl:vertScroll>
</form>

每当我提交时，它就会延伸。
此页面也在div内。我是否还需要设置div和表格的宽度？

使用table-layout:fixed该表，并word-wrap:break-word在TD。

请参阅以下示例：

<html>
<head>
   <style>
   table {border-collapse:collapse; table-layout:fixed; width:310px;}
   table td {border:solid 1px #fab; width:100px; word-wrap:break-word;}
   </style>
</head>

<body>
   <table>
      <tr>
         <td>1</td>
         <td>Lorem Ipsum</td>
         <td>Lorem Ipsum is simply dummy text of the printing and typesetting industry. </td>
      </tr>
      <tr>
         <td>2</td>
         <td>LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknown</td>
         <td>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</td>
      </tr>
      <tr>
         <td>3</td>
         <td></td>
         <td>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna...</td>
      </tr>
   </table>
</body>
</html>

演示：

table {border-collapse:collapse; table-layout:fixed; width:310px;}

       table td {border:solid 1px #fab; width:100px; word-wrap:break-word;}


       <table>

          <tr>

             <td>1</td>

             <td>Lorem Ipsum</td>

             <td>Lorem Ipsum is simply dummy text of the printing and typesetting industry. </td>

          </tr>

          <tr>

             <td>2</td>

             <td>LoremIpsumhasbeentheindustry'sstandarddummytexteversincethe1500s,whenanunknown</td>

             <td>Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</td>

          </tr>

          <tr>

             <td>3</td>

             <td></td>

             <td>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna...</td>

          </tr>

       </table>
