div中的表重叠（IE）（ASP.NET）

Question

我目前有两个正确浮动的div，但div内的内容相互重叠。这只发生在IE中。

tables overlapping in floated divs

这是我的css代码：

body {
    min-height:100%;
    height:100%;
    background-color:#ffffff;
    margin: 0px 0px 0px 0px;
}

.tableparent {
    position:absolute;
    top:70px; 
    left:50px;
    width:650px;
    height:650px;
    overflow:hidden;
}

.tableleft {
    width:325px;
    height:650px;
    float:left;
}

.tableright {
    width:325px;
    float:right;
}

.button {
    margin-top:535px;
}

这是我的.aspx：

<div class="tableparent">
    <div class="tableleft">
        <div class="table"> 
            <table id="tblModelRank" runat="server" align="right" cellpadding="5" >
