使用 href 抑制数组上方和下方的垂直空间

tag-icon • tag-icon spacing hyperref arrays
使用 href 抑制数组上方和下方的垂直空间

这是抑制阵列上方和下方的垂直空间？，与（下面的黑色框）一起使用时效果很好\fbox，但与（下面的青色框）一起使用时效果不佳\href。我的目标是消除href边界框似乎在array环境周围放置的多余垂直空间：

如果href边界框接近用途，\fbox那就没问题了。

答案1

\href并没有真正添加额外的填充空间，只是通过黑魔法添加了视觉链接边框，并没有真正反映文本框尺寸。

如果您在\fbox周围放置一个\href，您会看到 tex 框仍然受到限制，事实上，似乎仅使用\mbox就足以为 pdftex 提供所需链接边框尺寸的提示。
