在两个 HTML 表之间添加运输 Returns

Question

我有以下语法为我生成和创建两个 table。我遇到的问题是顶部 table 直接位于底部 table 之上。我想在两者之间添加一个 "buffer" 的白色 space。我尝试执行如下所示的 echo "<br><br>";，但要么是我将它放在错误的位置，要么是语法不正确。有人可以告诉我如何在两个 html table 之间添加 space 吗？

Answer 1

br 标签位置错误，您应该将它们放在第一个 table 标签之后，紧跟在第一个 </table> 标签之后（现在已丢失）

但更好的方法是使用 css 为 table 之一添加边距你可以先试试这个 table

<table style="margin-bottom: 10px;">
