带有下拉箭头的ASP.NET菜单间距问题

Question

我有一个ASP.NET菜单，对于包含下拉菜单的项目，它会在新的<td>中显示一个箭头，问题是间距太大了。如何点击<TD>或缩小菜单文本与箭头之间的间距？

菜单问题的屏幕截图：

HTML输出：

<td style="white-space:nowrap;">
<a class="ctl00_itemMenu_1 StaticMenuItemStyle ctl00_itemMenu_3" style="border-style:none;font-size:1em;" href="Default.aspx">&nbsp;Home&nbsp;&nbsp;</a>
</td>
<td style="width:0;">
<img style="border-style:none;vertical-align:middle;" alt="Expand Home" src="Images/menu_arrow.gif">
</td>

菜单控制：

<asp:Menu ID="itemMenu" SkinID="MenuSkin" runat="server" Orientation="Horizontal"
            CssClass="menu" DynamicItemFormatString="&nbsp;{0}&nbsp;&nbsp;" StaticItemFormatString="&nbsp;{0}&nbsp;&nbsp;"
            StaticEnableDefaultPopOutImage="true" StaticPopOutImageUrl="~/Images/menu_arrow.gif"
            DynamicPopOutImageUrl="~/Images/menu_arrow_dynamic.gif" DynamicEnableDefaultPopOutImage="true" 
            MaximumDynamicDisplayLevels="5">
            <StaticMenuStyle CssClass="StaticMenuStyle" />
            <StaticMenuItemStyle Width="100%" CssClass="StaticMenuItemStyle" />
            <StaticHoverStyle CssClass="StaticHoverStyle" />
            <DynamicMenuStyle CssClass="DynamicMenuStyle" />
            <DynamicMenuItemStyle CssClass="DynamicMenuItemStyle" Width="100%" />
            <DynamicHoverStyle CssClass="DynamicHoverStyle" />
        </asp:Menu>
