Worked on stabilizing table rendering in the iTwin/iTwinUI repository, focusing on resolving hydration mismatches between server-side and client-side rendering. Addressed a specific bug by disabling resizing for the ActionColumn in the Table component, which eliminated rendering discrepancies without altering the existing API or user experience. This targeted fix improved SSR and CSR consistency, reducing the likelihood of post-release hotfixes for data-heavy tables. The solution was implemented using React and TypeScript, leveraging front end development expertise to ensure maintainability and traceability. All changes were aligned with tracked issues, supporting future maintenance and preserving the stability of the codebase.
