+# Table Management API
+
+This document describes the Table Management API endpoints for managing restaurant tables in the POS system.
+
+## Overview
+
+The Table Management API allows you to:
+- Create, read, update, and delete tables
+- Manage table status (available, occupied, reserved, cleaning, maintenance)
+- Occupy and release tables with orders
+- Track table positions and capacity
+- Get available and occupied tables for specific outlets
+
+## Table Entity
+
+A table has the following properties:
+
+```json
+{
+  "id": "uuid",
+  "organization_id": "uuid",
+  "outlet_id": "uuid",
+  "table_name": "string",
+  "start_time": "datetime (optional)",
+  "status": "available|occupied|reserved|cleaning|maintenance",
+  "order_id": "uuid (optional)",
+  "payment_amount": "decimal",
+  "position_x": "decimal",
+  "position_y": "decimal",
+  "capacity": "integer (1-20)",
+  "is_active": "boolean",
+  "metadata": "object",

+
+## Example Usage
+
+### Creating a Table
+```bash
+curl -X POST http://localhost:8080/api/v1/tables \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <token>" \
+  -d '{
+    "outlet_id": "123e4567-e89b-12d3-a456-426614174000",
+    "table_name": "Table 1",
+    "position_x": 100.0,
+    "position_y": 200.0,
+    "capacity": 4
+  }'
+```
+
+### Occupying a Table
+```bash
+curl -X POST http://localhost:8080/api/v1/tables/123e4567-e89b-12d3-a456-426614174000/occupy \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer <token>" \
+  -d '{
+    "order_id": "123e4567-e89b-12d3-a456-426614174001",
+    "start_time": "2024-01-15T10:30:00Z"
+  }'
+```
+
+### Getting Available Tables
+```bash
+curl -X GET http://localhost:8080/api/v1/outlets/123e4567-e89b-12d3-a456-426614174000/tables/available \
