Question

您的代码中有很多错误和一些误解。

包scrpage2用于 KOMA-Script 类，如scrartcl。它已过时。您应该改用fancyhdr（对于不使用 KOMA-Script 的文档）或者您需要调用包scrextend才能使用包scrlayer-scrpage（的后继scrpage2）。
包caption2已过时，请改用包caption！
您的包裹hyperref应该最后被调用！
您使用了很多setlength命令。您最好使用包来实现这一点。请参阅带有...geometry的文档。texdoc geometry
您在使用字幕时犯了一些错误longtable：字幕末尾longtable需要一个。\\
您不能p仅在中使用longtable，它必须是类似于的。根据您的需要p{7.5cm}更改值！7.5cm
您在代码中使用了很多包和命令。您知道每个包和命令的作用吗？如果不知道，请删除/注释它们，检查布局中的变化并阅读每个包的文档！

以下更正后的代码编译时没有错误（但布局可能与您想要的不同）：

及其结果：

现在对您的使用进行一个注释\hyperref[frog]{frog}：如果您希望能够创建一个指向特殊单词的链接，例如frog在您的文本中，您需要使用hypertarget来定义链接的目标frog：\hypertarget{frog}{text of link frog}。然后，指向目标的链接将按照tex 代码中的格式frog写入...\hyperlink{frog}{text to link to frog}

正如您在以下较短的 mwe 中看到的，根据您更改的代码，您可以使用

\hyperlink{lb:EDM}{EDM} %\hyperref[lb:EDM]{EDM}

和

\hypertarget{lb:EDM}{ED M} \\ %\phantomsection{ED M}\label{lb:EDM}\\

在你的两个表中。
