我只是想弄清楚如何将多行引用到同一个脚注中。我曾经\usepackage{threeparttable}这样做过。但是，我制作的表格相当大（超过 70 行），这似乎弄乱了命令\centering。表格已向右移动。
现在，我正在使用 resizebox 将整个内容放入一页，并且我不太愿意随机选择，\renewcommand因为我并不总是确定这会对我的具体情况产生什么影响。
表格仍然在页面内，但我真的很想让它居中。
这是最小可行代码和表格的一部分。

很抱歉我说得这么枯燥，只是漫长的一天过后我感到很累，而那一行又一行的相同脚注却花了我太多时间才弄清楚。
答案1
您所描述的“表格向右移动”现象几乎肯定是一种视觉错觉，是由于表格有 11 列而导致非常宽造成的。
我强烈建议不要使用任何一种\resizebox机器adjustbox将表格塞进一页，因为这种技巧几乎肯定会导致材料变得太小，以至于完全难以辨认和理解。
相反，我建议你使用一个或多个横向模式页面来呈现表格。具体需要多少个页面取决于实际表格有多少行。
以下屏幕截图显示了在环境中渲染代码中提供的表格的结果sidewaystable。请注意，我使用了包中的一些机制siunitx来帮助自动格式化数字数据。如果您的表格需要在多个环境中显示sidewaystable，请务必使用包\ContinuedFloat中的宏\caption来帮助调整表格标题的编号。
恐怕我不懂冰岛语，但我忍不住要说，如果你能把数据列 1 和 2 上方的子标题写得不那么冗长，可能会很有用。:-)
