/**
 * A simple example tool demonstrating an editable table for managing company departments.
 * 
 * This tool provides:
 * - A clean, editable table interface
 * - Inline editing capabilities
 * - Row-level actions (edit/delete)
 * - Pagination and sorting
 * 
 * This is a great starting point for understanding the basic editable table pattern.
