这里有一些生成 pdf 的代码，并且已经稳定使用了几年 - 但是，我刚刚注意到生成的 pdf 在 acrobat reader 中不可搜索。如何使生成的 pdf 可搜索？
请注意，包含要搜索的内容的元素是一个表格 - 也许这就是问题所在？

谢谢 Marijn，那是票，我的错误：reportlab 生成的 pdf > 是< searchable already (from the .build call at the end of the code); the pdf subsequently generated by windows print to pdf is not searchable. Interesting, but, this particular question is solved.
