This is how I'm solving wide tables in midday: - Horizontal scrollable - Visible pagination if too wide - Keyboard navigation

Cursor MCP is a game-changer! We've just added a new page to the Cursor Directory to help you find them more easily: ◇ Discover popular MCPs ◇ Search and filter options ◇ Submit your own entries Link ⬇️🧵

I'll never write documentation again thanks to Cursor's @ codebase command

the perfect table, now: - Sortable &amp; resizable - Ultra performant with virtualization - Hide columns - 1-1 Skeleton - Fully SSR using cookies

Considering turning this Bubble menu into a copy-paste component. Let me know if you're interested! * Shadcn components * Vercel AI SDK * Novel editor

Customizable widgets with Next.js for SSR and interactivity is a killer combo: - dnd-kit for dragging - Zustand store with initial data - Saved in Redis - Preloaded using tRPC

if you have this table perf you shipped to late.

This is how I made this assistant interface with: - Canvas with dynamic data (charts, metrics, summary) - Generated message title - Multi part stream - Generated follow up questions 🧵 ⬇️

The best way to handle responsive tables: ◇ Measure width and add scroll ◇ Sticky columns for context ◇ Pagination ◇ Keyboard (Arrow left/right)

The usage of AI-powered filters is so nice and easy to implement with Vercel AI SDK: ◇ Server Action with streamObject ◇ Pass filters (categories, amount range, etc.) ◇ Stream the results using `readStreamableValue`

Generate skeletons in seconds with Cursor 🔥 Use `@ filename.tsx` command ⚡

You can now run your business straight from Raycast.

A collection of AI SDK tools deserves a website: - Devtools: a React Query devtool for AI SDK - Store: AI chat state that scales - Artifacts: a structured way to handle advanced interfaces 🔗 ⬇️
