I'll add success and failure notifications to your loading buttons:

Notification System for Success and Failure States

I've added a comprehensive notification system to your loading UI:

1. Updated Existing Buttons

I've enhanced your existing buttons to show notifications after loading:

• The first button now randomly shows success or error notifications (70% success, 30% error)
• The second button shows a success notification when data is loaded
• The progress button shows a warning notification when the process completes

2. New Notification Demo Component

I've also created a dedicated notification-demo.tsx component that showcases different notification types:

• Success Notification: Green-styled notification with success message
• Error Notification: Red destructive notification for error states
• Warning Notification: Yellow-styled notification for warning states
• Custom Notification: Blue notification with a custom icon

How the Notifications Work

The notifications use the shadcn/ui toast system:

1. Each notification has a title and description
2. Success notifications have green styling
3. Error notifications use the destructive variant (red)
4. Warning notifications have yellow styling
5. All notifications automatically dismiss after a few seconds
6. The custom notification demonstrates how to add icons or other elements

Implementation Details

• The notifications are triggered after the loading state completes
• Each button simulates a different outcome (success, error, warning)
• The notifications are styled differently based on their purpose
• The toast system handles positioning and animation

This notification system provides immediate feedback to users about the outcome of their actions, which is an essential part of a good user experience. Users know whether their action was successful or if they need to try again.

I'll keep the table as the main focus and integrate notifications with it:

Table with Loading States and Notifications

I've kept the table as the main focus and enhanced it with loading states and notifications:

Enhanced Table Features

1. Skeleton Loading

   • The table still has the skeleton loading state when data is being fetched
   • The toggle button now shows appropriate notifications when loading/showing data

2. Action Buttons with Loading States

   • Each row now has both Edit and Delete buttons
   • Buttons show loading spinners when clicked
   • Only the clicked button is disabled during processing

3. Contextual Notifications

   • Edit Action: Shows a success notification when the edit operation completes
   • Delete Action: Randomly shows success or error notifications (70% success, 30% error)
   • Toggle Table: Shows different notifications when loading or displaying data
   • Add User Button: Shows a notification with a custom icon

How It Works

1. Row-Level Loading States

   • Uses a processingId state to track which row is being processed
   • Only disables the specific button that was clicked
   • Shows loading spinner only on the active button

2. Notification Types

   • Success: Green notifications for successful operations
   • Error: Red destructive notifications for failed operations
   • Info: Default notifications for informational messages

3. User Experience

   • Users get immediate feedback on their actions
   • The loading states prevent multiple clicks on the same action
   • Notifications provide context about what happened

This implementation provides a complete user management interface with proper loading states and notifications, giving users clear feedback about the status of their actions.
