The issue requests adding CSS transition effects (e.g., fadeIn/fadeOut) for rows when they are inserted or removed from the table. To implement, you would need to modify the row component (likely in src/Row.js or similar) to apply a CSS class during mount/unmount. You can use CSS animations with opacity and transition properties, or integrate a library like react transition group. Check if the current code uses any animation hooks; otherwise, add a simple fade effect by toggling a class.
