【问题描述】：
我有一个非常具体的问题，我无法找到解决方案。 最近，我开始了一个项目，根据从晨星获得的特定数据，我正在监控大约 100 只 ETF 和共同基金。当前的解决方案效果很好 - 但后来我发现我需要来自网站内另一个“选项卡”的更多数据。具体来说，我正在尝试从以下网站的第一个表中获取数据：https://www.morningstar.dk/dk/funds/snapshot/snapshot.aspx?id=F00000Z1MC&tab=1
现在，我有下面的代码，用于从网站上的“Indhold”选项卡中的表格中抓取数据，并将其导出到 Excel。因此，我的问题是：如何调整代码以从网站的另一部分抓取数据？。
简要解释代码并重申：下面的代码从同一网站的另一个标签中抓取数据。很多很多的 ID 用于代表每个共同基金/ETF 的每个网站。设置工作得很好，所以我希望简单地调整它（如果可能的话）以从上面的链接中提取表格。我对该主题的了解非常有限，因此非常感谢任何帮助。
