ReactGrid 4.1.17 benchmarks: None, Cols and Span; editable payments, row and column mutations, printable view and memory information.
Full-data ReactGrid benchmark, not a paged or sampled substitute. Row mutations and panel selection use an application adapter:
ReactGrid 4 has no equivalent imperative CRUD / select-rows API. Native span is experimental; merged anchors use a custom double-click editor.
Large datasets can exceed browser memory or scroll-height limits. Libraries and styles load from ./reactgrid.bundle.js; accounts.js is optional but required for account names.
