LombokTableSheet

Fast, lightweight Table + Spreadsheet library. Framework-agnostic core, thin adapters for React/Vue/vanilla JS. A Table + Spreadsheet library, built with a portable core so it can be implemented once and translated across languages. Started as a TypeScript/JavaScript core; has a PHP port of the data/formula layer, verified byte-identical to the TS

Features

Fast, lightweight Table + Spreadsheet library. Framework-agnostic core, thin adapters for React/Vue/vanilla JS. Apache 2.0.
Fast: virtualization-ready data model, sparse storage, no framework tax in the core.
Simple: one small, dependency-free core; adapters are thin wrappers, not reimplementations.
Portable: the core is written so it can be mechanically ported to PHP, Go, and Rust (planned — see roadmap). No eval, no reflection magic, no host-language tricks.
International: Intl-backed number/date/currency formatting, RTL support, UI string catalog for 11 languages out of the box.
Unique from the pack: templates are pure JSON/CSS, never coupled to your data — export to CSV/JSON and the presentation concerns disappear entirely.
