Contributed to the Tencent/cherry-markdown repository by enhancing the ECharts code block plugin and improving streaming table rendering reliability. Focused on front end development using JavaScript, HTML, and ECharts, the work introduced support for function syntax in option parsing, enabling more dynamic chart configurations. Performance was optimized by preventing redundant setOption calls when chart data remained unchanged. Additionally, addressed a streaming table issue by escaping HTML attribute values and cleaning up cursor placeholders, which improved serialization and streaming stability. These changes collectively strengthened the rendering pipeline’s performance, correctness, and maintainability, supporting more robust dynamic content in markdown environments.
