研究方向
Investigate the table component's scroll handling logic, particularly the virtualization mechanism. Check if the issue is related to incorrect clipping or missing update events when scrolling more than 3 lines. Look into the Table component's scrolling implementation in the Blueprint repository, focusing on files like `table/src/table.tsx` and related scroll event handlers.
