e-virt-table is a high-performance, canvas-based virtual data table library designed for building spreadsheet-like grids in web applications. It renders tens of thousands of rows and columns using a custom canvas drawing engine with virtual scrolling, fixed columns, cell editing, selection, autofill, copy/paste, sorting, filtering, tree data, cell merging, and undo/redo. The library is framework-agnostic (usable in plain JS, Vue 2/3, and React) and is distributed as an npm package with UMD/ESM/CJS formats. Its architecture follows a modular event-driven pattern: a central Context class manages state and communication between subsystems (Selector, Editor, Database, Scroller, History, Validator, FinderBar, etc.), while a Paint module abstracts canvas drawing operations. The configuration surface is extensive (~100 options via CSS variables and a Config object), enabling deep customization of appearance and behavior. The repository also includes a bilingual VitePress documentation site with hundreds of interactive examples, as well as a dev playground and a suite of system-level tests for border rendering and scrollbar modes.
