基类：Mapper

Extracts tables from HTML content and stores them in a specified field.

This operator processes HTML content to extract tables. It can either retain or remove HTML tags based on the retain_html_tags parameter. If retain_html_tags is False, it can also include or exclude table headers based on the include_header parameter. The extracted tables are stored in the tables_field_name field within the sample's metadata. If no tables are found, an empty list is stored. If the tables have already been extracted, the operator will not reprocess the sample.
