What changed
The HTML parser now tracks cell span attributes and reconstructs them in the Markdown output using repeated cell content and alignment markers. Tables with multi-level headers retain their grouping, and data cells that span multiple columns are represented with clear visual indicators.
Practical impact
Financial reports, specification sheets, and comparison matrices exported from web dashboards now convert without manual table repair. For tables exceeding 20 columns, the output includes a collapsible structure hint so downstream LLM pipelines can parse the hierarchy correctly. Feedback: sapsap@qq.com.
