VxeTable is a Vue 3 component library for building complex, enterprise-grade data tables and grids. It provides a comprehensive set of features including virtual scrolling for millions of rows, inline editing, Excel-style copy-paste, column resizing/dragging, filtering, sorting, pivot tables, tree/gannt views, and export/import/print. The library is architected as a set of Vue components (VxeTable, VxeGrid, VxeColumn, VxeToolbar, VxeColgroup) with an extensible plugin system based on hooks and renderers. It relies on a companion UI library (vxe-pc-ui) for modals, buttons, selects, and other controls, and uses xe-utils for utility functions. The codebase is large and well-organized, with separate modules for editing, filtering, keyboard navigation, validation, column customization, and export. Performance is a key focus, with virtual scrolling implemented for both X and Y axes. The library supports i18n with over 20 languages and includes a comprehensive theming system with light/dark modes. While primarily a UI component library, it also includes proxy-based server-side data operations in the VxeGrid component. The repository includes a demo application (examples/) for testing features, though the main artifact is the published npm package.
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.
