感謝這篇文章長桌與三部曲桌（但我無法評論，因為我是新來的）我發現如果我使用 Threeparttable 包，我可以將腳註與 longtable 一起使用。
但是，我想在筆記上方添加一行。有人知道該怎麼做嗎？ （我想要這樣的東西）
這是我的程式碼的範例。表 1（longtable）是帶有 ThreePartTable 套件的腳註的表。它沒有在音符之上。表 2（有小型頁面環境）在註釋上方有一行。我想要表 1 中的類似行。

感謝伯納德，問題解決了！
使用 ThreePartTable 在腳註上方放置水平線的方法（類似於 minipage 環境的腳註）是：
\noalign {\rule [-1.4ex]{6.7cm}{0.4pt}}
