Html Div标记中存在错误

行中出现错误：错误是div标记中的位置无效，并且div标记未正确结束。但是我已经结束了div标签。。sombody能否告诉我为什么会出现此错误。

根据您发布的代码，最外层的表和一些div标记未关闭。整个代码段应该是这样的

<table style =" border-collapse :collapse ; width :100px ; height: 100px ; align:centre:">
        <tr style="height :100%">
        <td dir="ltr" style="width:100px; vertical-align :top">
        <div class="portletContainer" >
        <div style="width:464px;margin-top:-1px; margin-left:7px;">
                <table id="pendingActivity" style= "border-collapse ;collapse ; border-right:1px solid #ddd; border-left:1px solid #ddd; border-bottom:1px solid #ddd">
