Question

下拉菜单在Chrome中运行良好，但嵌套UL（弹出的列表：悬停）的位置并不直接位于Internet Explorer或Firefox中的父LI下方。在IE和FF中，嵌套的UL菜单拥抱整个NAV的左侧而不是其父LI。

知道我错过了什么吗？

CSS：

nav {
    clear: none;
    float: right;
    font-family: 'Open Sans';
    line-height: 120px;
}


nav ul {
    position: relative;
    display: inline-table;
}


nav li {
    display: inline;
    padding-left: 5px;
    position: relative;
}

nav a, nav a:visited {
    font-size: 14px;
    padding: 8px;
    text-transform: uppercase;
    text-decoration: none;
    color: #005f99;
}

nav a:hover, nav a:active {
    color: #fff;
    background-color: #7fafcc;
    /*border-bottom: 2px solid #5cbc51;*/
}

nav li.current a {
    color: #fff;
    background-color: #7fafcc;
    /*border-bottom: 2px solid #5cbc51;*/
}

nav li ul {
    display: none;
}

nav ul li:hover > ul {
    display: block;
}

nav ul ul {
    position: absolute;
    top: 29px;
    padding: 0;
    margin: 0 0 0 5px;
    background-color: #005f99;
    width: 200px;
    z-index: 999;
}

nav ul ul li {
    padding: 0;
    margin: 0;
    float: none;
    position: relative;
    display: block;
    clear: both;
    color: #fff;
    border-left: 4px solid #fff;
    border-bottom: 1px solid #fff;
}

nav ul ul li:hover {
    background: #22284f;
}

nav ul ul li a, nav ul ul li a:visited {
    font-size: 14px;
    line-height: 20px;
    text-transform: uppercase;
    text-decoration: none;
    color: #fff;
    display: block;
    width: 100%;
}

nav ul ul li a:hover, nav ul ul li a:active {
        color: #fff;
    background-color: transparent;
}
nav ul ul li {
    line-height: 40px;
}


nav ul ul li { border-color: #35b5eb; }
nav ul ul li+li { border-color: #0acf67; }
nav ul ul li+li+li { border-color: #f2c13f; }
nav ul ul li+li+li+li { border-color: #a5c950; }
nav ul ul li+li+li+li+li { border-color: #ab50c9; }
nav ul ul li+li+li+li+li+li { border-color: #eb5b4c; }

HTML：

  <nav>  <ul>
            <li class="current"><a href="" title="">home</a></li>
            <li><a href="" title="">about us</a>

                    <ul>
                    <li><a href="">Our Mission</a></li>
                    <li><a href="">History &amp; Impact</a></li>
                    <li><a href="">Financials</a></li>
                    <li><a href="">Staff</a></li>
                    <li><a href="">Board Members</a></li>
                    <li><a href="">Careers & Jobs</a></li>
                    </ul>

            </li>

            <li><a href="" title="">get involved</a></li>           
            <li><a href="" title="">stores</a>
            <ul>
                    <li><a href="">Our Mission</a></li>
                    <li><a href="">History &amp; Impact</a></li>
