Python Generate tables in PDF(2)

接着上一篇博客继续实现PDF中表格的绘制：https://blog.csdn.net/m0_37690102/article/details/107051058

• Then on a blog to continue to implement drawing in PDF form: https://blog.csdn.net/m0_37690102/article/details/107051058

直接上代码：在上一篇博客中，您已经能够简单的能在PDF中生成相应的表格了，但是还是存在一点点小问题，对于表格内部的文字信息没办法直接写入，已经表格不属于连通区域的。

• Code directly: In the last blog post, you were able to easily generate tables in PDF, but there is still a small problem. The text information inside the table cannot be written directly, and the table does not belong to the connected area.

完整的代码您可以参考下面我给出的，如果存在相应的问题，请您及时和我联系，非常感谢您的反馈。

• You can refer to the complete code below. If there is any problem, please contact me in time. Thank you very much for your feedback.
