每个长表一个书签

每个长表一个书签

几个月前，我问了一个关于如何为表格和图形生成书签的问题，并得到了一个很好的答案（已解决的问题）。

建议的代码对于普通表格来说非常有效。但是，我很难找到一个适合长表格的好的解决方案。在下面的代码中，我为显示长表格的每个页面获取一个书签，并且所有书签都指向同一页面。理想的解决方案是每个长表格只有一个书签，并且书签当然应该指向长表格的第一个标题。

此外，longtable 的书签名称是部分的名称。我假设 longtable 不会更改 currentlabelname，但我不确定是否可以在 longtable 环境中手动更改 currentlabelname。

我已经尝试解决这个问题很长时间了，但一直没能找到一个好的解决方案。任何建议都非常感谢。

Heiko 可能会使用适当的界面发布一些内容，但您可以强制该值\currentlabelname并测试该值，并且仅有条件地制作书签：
