我需要你的帮助。

每当用户向下滚动表格时，表格标题的顶部和底部边框都会消失。一旦用户到达表格
的底部，表格标题的顶部和底部边框就会重新出现。你如何解决这个问题？我正在使用 IE7 并且需要代码以符合该特定浏览器。

<!DOCTYPE html>

<style type="text/css">

table a:link {
    color: #666;

第二天用新的眼光玩了一些 css 之后，以下适用于 IE7：

<style type="text/css">

/*------------------------------------------------------------------
Table Style
------------------------------------------------------------------ */
table a:link {
    color: #666;
    font-weight: bold;
    text-decoration:none;
}
table a:visited {
    color: #999999;
    font-weight:bold;
    text-decoration:none;
}
table a:active,
table a:hover {
    color: #bd5a35;
    text-decoration:underline;
}
table {
    font-family:Arial, Helvetica, sans-serif;
    color:#666;
    font-size:12px;
    background:#eaebec;
    border-radius:3px;
    border-collapse:collapse; border-spacing: 0; 
    box-shadow: 0 1px 2px #d1d1d1;
    border-left: 1px solid #ccc;
    border-right: 1px solid #ccc;
}
table th {
    padding:10px 10px 10px 10px;
    border-bottom:1px solid #ccc;
    border-left: 1px solid #ccc;
    background: #ededed;
}   
table tr {
    text-align: center;
}   
table td {
    padding:10px;
    border-bottom:1px solid #ccc;
    border-left: 1px solid #ccc;

    background: #fafafa;
}   
table tr:hover td {
    background: #f2f2f2;
}
table th, table td {
    width: 160px; 
}
#container {
    width: 800px;
    height: 300px;
    overflow-x: scroll;
    overflow-y: scroll;
}
table tr td:first-child, table tr th:first-child {
    border-left: 0;
}

table thead {
    position:fixed;

}

TABLE THEAD TR TH {
    top:expression(this.offsetParent.scrollTop);
    border-top:1px solid #ccc;
    position:relative;
}

table tr:first-child td {
    border-top: 0;
}
</style>

海我刚刚在下面修改了你的 CSS 代码，请试试这个。

table thead {
    position:fixed;

}
table thead tr {
    position: relative;

}
