从 PDF 中的嵌套表格中提取数据
我有一些从 Word 或 Excel 文件创建的 pdf 文件。
我需要获取表格中的信息。
文档中的文本不是图像，因此我可以使用 pdfbox 等工具提取文本。
当我有文本时，我无法知道它属于表格中的哪些单元格，因为我不知道表格边框在哪里。
我尝试了一些桌面工具，例如 abby 或 Solid pdf Converter，它们能够将文件转换为漂亮的 Word 文档，但这不适合我的需求，因为我希望能够在 C# 中以编程方式完成此操作.
有些表有嵌套表，我认为这使得这有点困难。
我感谢你的帮助
I have a few pdf files that were created from word or excel files.
I need to get the information thats in the tables.
The text in the document is not an image so I'm able to extract the text using tools such as pdfbox.
When I have the text I have no way of knowing what cells in the table it belongs to because I don't know where the table borders are.
Iv'e tried a few desktop tools such as abby or solid pdf converter and they are able to convert the files into nice word documents but this doesn't suit my needs as I want to be able to do this programatticly in C#.
Some of the tables have nested tables wich I think makes this a little bit more diffucult.
I appreciate your help

这里的困难是由于 PDF 中的文本不包含在任何表格中。看起来可能是这样，但在表面之下，事实并非如此。
所以我能想到几个选择。但它们都不会像您希望的那样令人满意。
这是一项艰巨的任务，但希望这会给您一个起点。
The difficulty here is caused by the fact that the text in the PDF is not contained within any table. It might look like it is, but underneath the surface, it is not.
So there are a couple of options that I can think of. But none of them are going to be quite as satisfying as you'd probably like.
It's a difficult task, but hopefully this will give you a starting point.
