Question

我只是想知道，因为我没有这样做，我是否在促销箱中的桌子内获得了navmenu并且在白色空间的顶部居中并且在顶部中心框/ td / cell上没有边框帮助会很重要，因为它很重要。

如果没有jsfiddle示例，您的问题就会模糊不清。请在jsfiddle上向我们展示实时示例。

如果您在菜单顶部的表格中获得空格，请在表格标签上设置cellspacing =“0”

<table cellspacing="0">

要让您的菜单位于表格中间，请使用display: inline-block;上的ul#navmenu li和ul#navmenu a代替浮点数，并将text-align: center;放在ul＃navmenu上

浮点元素不能以margin为中心：auto或text-align：center这就是我们必须更改要显示的元素行为的原因：inline-block将每个元素放在一起，并使其成为父元素的中心。< / p>

在表格的td内没有边框的导航菜单对齐
