我尝试创建一个长表，但它不起作用。我有两个问题：
- 表格在以下页面中创建（我尝试使用 longtable 包来解决这个问题但似乎不起作用）。
- 长表的标题出现在一个奇怪的位置。
附件是我的代码和结果。如果有人能帮助我，我将不胜感激！

答案1
正如@DavidCarlisle 在评论中已经指出的那样，首先要摆脱\centering、adjustbox和tabular。
为了使表格适合文本块的宽度，您应该允许所有 8 列自动换行。我还会删除粗体显示第 4 列和第 8 列中的数字，并将它们与各自的小数点对齐。（不要过度使用粗体，除非你故意想给人留下喜欢冲人大喊大叫的印象……）并且，为了给标题材料提供更多的视觉结构，请考虑将单位声明放在单独的行上。
下面的截图只显示了结果表的前几行。
