Extract Tables from PDF ​

Overview ​

To extract table content from a PDF document.

Standard table and non-standard table ​

Commonly, tables can be divided into two categories: standard tables and non-standard tables. The specific definitions are as follows:

• Standard table: The table border and the inner lines of the table are complete and clear. There is no need to manually add table lines to divide the table content.

• Non-standard tables: Table borders or inner lines are missing, and table lines are unclear. Table lines need to be manually added to separate the table content.

Note ​

• Non-standard tables in the original PDF document cannot be extracted when the OCR option is not enabled.
• It is recommended to enable OCR or AI layout analysis options for higher accuracy of table extraction and the support of non-standard table recognition.
