Potential improvements

• Error handling: Currently the app will display a blank page if an error occurs while fetching the schedule data. Ideally it should catch the error and display a useful message.
• Responsiveness: The table will perform basic wrapping at smaller screen sizes, but this could be fine-tuned with explicit breakpoints.
• Accessibility: The table should have some ARIA attributes to connect the data with the associated labels.
