将HTML替换为我的
<div style="width:60%;margin-left:30%">
<a class="button" data-table="1" href="#">button</a>
<a class="button" data-table="2" href="#">button</a>
<a class="button" data-table="3" href="#">button</a>
<a class="button" data-table="4" href="#">button</a>
</div>
关键是将所有按钮放在div的宽度与表格相同的位置，然后将按钮居中。
答案 1 :(得分：0)
它已经以你的桌子为中心。
你有
th:first-child {
background: none;
}
所以你看不到桌子的这一部分。
删除background: none;，您将能够看到它居中。

此外，如果您使用的是HTML5，请不要使用<center>标记，因为它们在HTML5中已弃用。只需使用<div>代码，然后为其提供text-align: center;
答案 2 :(得分：0)
我从你不想看到th的第一个孩子的事实出发，如果是这样的话，我建议你删除每行中的那些行以及css文件中对它的引用。
