尝试把一个表格实现的Vertical菜单，改用div来实现。

原代码如下：

Vertical Menu by Table <table cellpadding="5" cellspacing="1" width="100%" border="0">
    <tr>
        <td bgcolor="white" height="3px">
        </td>
    </tr>
    <tr>
        <td height="15px" bgcolor="#dcdcdc" onmouseover="this.style.backgroundColor='faf0e6'"
            onmouseout="this.style.backgroundColor='dcdcdc'">
            &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;<asp:HyperLink
                ID="HyperLink1" runat="server" Text="Hperlink1" NavigateUrl="~/Default1.aspx"
                ></asp:HyperLink>
        </td>
    </tr>
    <tr>
        <td bgcolor="white" height="1px">
        </td>
    </tr>  
      <tr>
        <td height="15px" bgcolor="#dcdcdc" onmouseover="this.style.backgroundColor='faf0e6'"
            onmouseout="this.style.backgroundColor='dcdcdc'">
            &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;<asp:HyperLink
                ID="HyperLink2" runat="server" Text="Hperlink2" NavigateUrl="~/Default2.aspx"
                ></asp:HyperLink>
        </td>
    </tr>
    <tr>
        <td bgcolor="white" height="1px">
        </td>
    </tr>  
</table>

使用Div tag来实现vertical菜单，首先来看看效果：

为菜单设置样式：

Div Menu Style  #div_menu
    {
        margin-top: 2px;
        margin-bottom: 2px;
        padding: 5px;
        background-color: #dcdcdc;
        height: 16px;
    }  

菜单：

Menu <div style="background-color: #FFFFFF; height: 3px;">
</div>
<div id="div_menu" onmouseover="this.style.backgroundColor='faf0e6'" onmouseout="this.style.backgroundColor='dcdcdc'">
    &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;
    <a href='<%= ResolveUrl("~/Default1.aspx") %>'>
        Hyperlink1</a>
</div>
<div id="div_menu" onmouseover="this.style.backgroundColor='faf0e6'" onmouseout="this.style.backgroundColor='dcdcdc'">
    &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;
    <a href='<%= ResolveUrl("~/Default2.aspx") %>'>
        Hyperlink2</a>
</div>
<div id="div_menu" onmouseover="this.style.backgroundColor='faf0e6'" onmouseout="this.style.backgroundColor='dcdcdc'">
    &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;<a
        href='<%= ResolveUrl("~/Default3.aspx") %>'>Hyperlink3</a>
</div>
<div id="div_menu" onmouseover="this.style.backgroundColor='faf0e6'" onmouseout="this.style.backgroundColor='dcdcdc'">
    &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;
    <a href='<%= ResolveUrl("~/Default4.aspx") %>'>
        Hyperlink4</a>
</div>
<div id="div_menu" onmouseover="this.style.backgroundColor='faf0e6'" onmouseout="this.style.backgroundColor='dcdcdc'">
    &nbsp;&nbsp;<img src='<%= ResolveUrl("~/link.gif")%>' align="absmiddle" />&nbsp;&nbsp;<a
        href='<%= ResolveUrl("~/Default5.aspx") %>'>Hyperlink5</a>
</div>
