Python Camelot:table_区域和table_区域未按预期工作
好几天来，我一直试图让Camelot在pdf页面的特定区域工作，但这一直让我感到困惑。我查看并尝试了文档建议和一些bug报告，但没有结果。我需要一些帮助 我从文档中选取了一个示例，因为它有多个表。我修改了原始命令，仅从以下两个表中提取一个：Python Camelot:table_区域和table_区域未按预期工作,python,pdf,python-camelot,Python,Pdf,Python Camelot,好几天来，我一直试图让Camelot在pdf页面的特定区域工作，但这一直让我感到困惑。我查看并尝试了文档建议和一些bug报告，但没有结果。我需要一些帮助 我从文档中选取了一个示例，因为它有多个表。我修改了原始命令，仅从以下两个表中提取一个： tables=camelot.read\u pdf（'12s0324.pdf'，flavor='stream'，strip\u text='.\n'） 致： tables=camelot.read\u pdf（'12s0324.pdf'，flavor='st
tables=camelot.read\u pdf（'12s0324.pdf'，flavor='stream'，strip\u text='.\n'）tables=camelot.read\u pdf（'12s0324.pdf'，flavor='stream'，strip\u text='\n'，table\u area=['33297386,65']，pages='1'）- 我更改了正则表达式，因为它消除了单词之间的空格
- 使用
代替文档的table_area
，因为前者触发细化，而第二个触发错误（错误已解释，文档似乎仍然错误）table_area - 尝试提取两个表，并使用中解释的camelot的绘图功能检查各自的区域，因此它们应该是正确的
- 也尝试过使用
，它至少拉出了一个表而不是两个表，但仍然相当不准确（请参见下面的注释）表\u区域
'35591385343'表格区域
只有一个表，显然，相同的问题在所选区域之外有不需要的文本
第三：在'33297386,65'
PDF区域（底部表格）上使用表格区域
更好的是，它会像上面那样拾取不需要的文本
我非常重视建议或建议。提前谢谢 table_area（而不是table_area）关键字参数工作良好，应该使用（我使用Camelot 0.7.3）
返回：
这似乎是对的。我现在更困惑了。我已经多次使用该命令（我刚刚检查过，我的Python控制台中仍然有一个实例），但它从未起作用。现在它是：P好的，感谢您确认表_区域
是正确的，与我所指的链接相反。我想知道他们为什么还把桌上的地方到处乱放。
