我对 LaTeX 还很陌生，所以请原谅我的无知。
以下是我的源代码的一部分。您会注意到我使用了环境\vspace之间_history。我知道我可以添加到的\vspace最后一个，但这意味着最后一个将包含间距。有没有办法将 添加到，除了周围环境中的最后一个之外的所有（在本例中）？{}\newenvironment_history\vspace_history_history_section
为了将其与 CSS 进行比较，我们可以执行以下操作：
_section:not(:last-child) {
...
}

答案1
我将跳过长度作为可选参数，_history默认值为 (基于您的代码) 2pt。在最后一次调用时，将其[0pt]作为可选参数传递。
