Worked on the zed-industries/zed repository to deliver an adaptive grid columns auto-size feature, enhancing the GPUI styling API for more responsive and content-aware UI layouts. Focused on improving the rendering of tables in Markdown previews and agent panel interfaces, the solution allowed borders to closely follow content rather than stretching across the full container. The implementation involved cross-module changes in Rust, touching files such as style.rs and markdown_renderer.rs, and emphasized maintainability and consistency across the front end. The work included end-to-end testing and manual validation, with comprehensive release notes to support ongoing development and user experience improvements.
