how to get the parameter value of table_areas? #358

I think add a param of table_areas when using read_pdf function could be better to extract table from pdf file, but where can I get the value of table_areas? I just tried using pdfplumber.open (x.pdf) to get all the items ( each items has its pdf coordinates and width\ height) in one page of pdf file, and I took the pdf coordinate of four corner items as the param values of table_areas , however it didn't work and it was even worse than purely read_pdf function without the table_areas param. I wonder if camelot could detect the pdf coordinate of table's areas or items in the table.

You can do some visual debugging.

Thank you .But how to get the dynamic picture? having followed the visual debugging, I found the picture I made was static so I can not get the precise coordinate of the table.

Don't know.

But if you don't have the precise coordinates, you can specify a broader area, using table_regions (https://camelot-py.readthedocs.io/en/master/user/advanced.html#specify-table-regions).

Ok, thank you so much. I think that is a good solution.
