/**
|
||||
* Key Patterns Demonstrated:
|
||||
*
|
||||
* 1. TanStack Table Integration: Using @tanstack/react-table with shadcn/ui
|
||||
* 2. Sorting: Click headers to sort ascending/descending
|
||||
* 3. Filtering: Text input to filter table data
|
||||
* 4. Column Visibility: Toggle columns via dropdown menu
|
||||
* 5. Pagination: Built-in pagination controls
|
||||
* 6. Row Actions: Dropdown menu per row for context actions
|
||||
* 7. Responsive Design: Table adapts to different screen sizes
|
||||
*
|
||||
* Required Dependencies:
|
||||
* - @tanstack/react-table
|
||||
* - lucide-react
|
||||
*
|
||||
* Installation:
|
||||
* npx shadcn@latest add table
|
||||
* npx shadcn@latest add button
|
||||
* npx shadcn@latest add input
|
||||
* npx shadcn@latest add dropdown-menu
|
||||
* npm install @tanstack/react-table lucide-react
