如何实现表格中内容的自动换行

我在页面中做了一个表格,用来显示数据库中内容详细一览的信息,可是当内容很长的时候,不能实现自动换行,这时表格会在一行显示,当然表格就很长了,表格代码如下:<table border="1"  table-layout="fixed">
<tr>
<td class="label1" height="30">カテゴリ：</td>
<td class="settle1" width="650" table-layout="fixed"><bean:write name="inputForm" property="categoryID"/></td>
</tr>
<tr>
<td class="label1" height="30">鉄則NO：</td>
<td class="settle1"><bean:write name="inputForm" property="tesokuNO"/></td>
</tr>
<tr>
<td class="label1" height="30">鉄則：</td>
<td class="settle1"><bean:write name="inputForm" property="tesokuName"/></td>
</tr>
<tr>
<td class="label1" height="70">状況・場面:</td>
<td class="settle1" height="60"><bean:write name="inputForm" property="tesokuStatus"/></td>
</tr>
<tr>
<td class="label1" height="70">解説:</td><td class="settle1"><bean:write name="inputForm" property="tesokuKaisetu"/></td>
</tr>
<tr>
<td class="label1" height="70">対処方法:</td><td class="settle1"><bean:write name="inputForm" property="tesokuTaisixyo"/></td>
</tr>

<tr>
<td class="label1" height="70">違反時事象:</td><td class="settle1"><bean:write name="inputForm" property="tesokuIhan"/></td>
</tr>
<tr>
<td class="label1" height="30">ランク:</td><td class="settle1"><bean:write name="inputForm" property="tesokuRanku"/></td>
<html:hidden name="inputForm" property="tesokuRanku"  value=""/>
</tr>
<tr>
<td class="label1" height="70">備考:</td><td class="settle1"><bean:write name="inputForm" property="tesokuBikou"/></td>
</tr>
<tr>
<td class="label1" height="30">発言立場:</td><td class="settle1"><bean:write name="inputForm" property="tesokuSonota"/></td>                 
</tr>
<tr></tr>
<tr><td></td>
<td align="center"><html:button property="" onclick="goBack()" value="戻る"></html:button>
</td>
</tr>
</table>里面也用了table-layout="fixed" 属性使其换行,但为什么不能实现换行呢
