Worked on enhancing table component rendering for complex multi-header scenarios across the Tencent/tdesign-vue-next and Tencent/tdesign-vue repositories. Addressed header rendering by implementing accurate colspan calculation and recursive header processing, ensuring correct display of nested columns and merged cells. Leveraged TypeScript and Vue.js to optimize column processing logic, which improved both correctness and performance for advanced table structures. The work included delivering a new feature for robust header rendering and fixing a bug related to colspan handling, resulting in reduced rendering errors and greater consistency between repositories. Focus remained on component development and front-end reliability using modern JavaScript frameworks.
