Documentation Hub:

• AIRTABLE_DOCS_INDEX.md - Complete navigation with FAQ
• docs/index.md - Updated to include roadmap section

Gap Analysis Summary

Current State (✅ 45 features):

• Data layer: 20+ field types, MongoDB + PostgreSQL drivers
• Query: JSON-DSL, complex filtering, lookup expansion
• UI: DataTable (Grid), AutoForm, Chart components
• API: REST endpoints, Swagger, authentication

Missing (❌ 62 features):

• View system: Form, Kanban, Calendar, Gallery, Timeline
• Interactions: Grouping, inline editing, bulk operations
• Collaboration: Comments, activity log, real-time sync
• Tools: CSV/Excel import/export, automation, templates

Implementation Roadmap (6 Phases)

Phase 1 (6w)  → Multi-view foundation (Form, Kanban, Gallery)
Phase 2 (4w)  → Data interactions (Grouping, inline edit, bulk ops)
Phase 3 (4w)  → Advanced views (Calendar, Timeline)
Phase 4 (5w)  → Collaboration (Comments, import/export, WebSocket)
Phase 5 (4w)  → UI polish (Rich text, attachments, field types)
Phase 6 (4w)  → Automation (Visual builder, templates)

Three Implementation Options

Option	Duration	Cost	Scope
A - MVP	3 months	¥400-500K	Phase 1-2 core features
B - Full ⭐	6 months	¥1.2-1.5M	Phase 1-5 complete (recommended)
C - Enhanced	7 months	¥1.4-1.8M	Phase 1-6 + AI features

Quick Wins (1-2 weeks)

Immediately implementable improvements identified:

• Virtual scrolling for 1000+ records
• Enhanced filters (date picker, type-specific inputs)
• Basic CSV export
• Improved lookup field display
• Keyboard shortcuts (Ctrl+Enter, Esc, Delete)

Technical Approach Highlights

View Architecture:

interface ViewConfig {
  type: 'grid' | 'form' | 'kanban' | 'calendar' | 'gallery' | 'timeline';
  object: string;
  filters?: FilterExpression[];
  groupBy?: string[];
  settings?: Record<string, any>;
}

Metadata Plugin:

loader.use({
  name: 'view',
  glob: ['**/*.view.yml'],
  handler: (ctx) => registerView(ctx.registry, yaml.load(ctx.content))
});

Success Metrics Defined

• Functionality: 6+ view types, advanced filtering, collaboration
• Performance: <2s for 1K records, <30s for 10K import, <500ms view switch
• Quality: >70% test coverage, 100% TS types, >90% docs

Original prompt

帮我评估，如果要实现基础Air table的功能，还需要做哪些开发，然后安排任务
