下了个最新RC3的版本，当table的width属性使用百分比时，出现了javascript提示：“参数无效”的错误。Me.initScroll里的
alert(twidth);   //twidth的值是负数，我这里显示的是-20；p取得的是px；
divSX.style.width=twidth+p;

我这里没有这情况啊

能否把jsp代码发来看看

谢谢了

页面代码如下：
<div id="tableDiv">
    <ec:table items="list" var="list"
    tableId="usersTableId"
        action="${pageContext.request.contextPath}/recycleList.do"
             
        toolbarLocation="bottom"
        nearPageNum="2"
maxRowsExported="400"
toolbarContent="status|export|navigation|pagejump|extend|pagesize|"

pageSizeList="max:100,10,15,30,50,100,all"

minColWidth="10"
resizeColWidth="true"
width="100%"
listHeight="440px" >

      <ec:row ondblclick="selectRowByOndbclick(this);">
          <ec:column property="no_such_property" title="选择" width="5%">
              <input id="${pageScope.list.expopersonid}" name="a" type="checkbox"  onclick="changeColor(this)" title="也可以通过双击这一列来选中框框"/>
           </ec:column>
                       
      <ec:column property="cardshamdeltime" title="删除时间" width="8%"/>
           
      <ec:column property="相片"  width="6%" style="height:70">

        <ec:column property="姓名" width="8%">
           <html:link action="/personView.do?personid=${pageScope.list.person.personid}" onclick="switchFrame()">

         </ec:column>
          
        <ec:column property="国家地区" width="8%">
            ${pageScope.list.person.country.countryname}
          <c:set var="provincename" scope="page">
        ${pageScope.list.person.province.provincename}
      </c:set>
      <c:if test="${pageScope.provincename !=null}">
${pageScope.list.person.province.provincename}
       </c:if>
        </ec:column>
           
      <ec:column property="所属代表团" width="10%">
        <input type="hidden" value="${pageScope.list.person.user.userid}"/>
           ${pageScope.list.person.user.company.team.teamname}
      </ec:column>
           
       <ec:column property="单位名称" width="15%">
            ${pageScope.list.person.user.company.companyname}
       </ec:column>
           
        <ec:column property="职位">
           ${pageScope.list.person.placename}
        </ec:column>           
           
       <ec:column property="审批状态">
        <input type="hidden" value=" ${pageScope.list.status.statusid}">
<c:set var="statusid" scope="page">
   ${pageScope.list.status.statusid}
</c:set>
    <c:if test="${pageScope.statusid != '2'}">
<font color="#ff0000">
${pageScope.list.status.statusname}
</font>
     </c:if>
      <c:if test="${pageScope.statusid == '2'}">
<font color="#000000">
${pageScope.list.status.statusname}
</font>
       </c:if>
       </ec:column>
                       
      <ec:column property="备注" width="6%">
            ${pageScope.list.person.notes}
       </ec:column>
           
  </ec:row>
       
</ec:table>
   </div>

没办法我只好改了twidth ，用document.body.clientWidth后现在可以实现了
var twidth = document.body.clientWidth;
//var twidth = ECSideUtil.parseIntOrZero(tableBox.style.width);

twidth=twidth-ECSideConstants['SCROLLBAR_WIDTH'];

这个问题我来回答：
<div id="tableDiv" style="width:100%">加上style就行。不管里面的内容是什么...

这样才能判断twidth。

fins演示的parentNode是body，可以直接取到。

谢谢bjwulin
