…dy cell F1-A2) Additive, virtualization-first compound table (VirtualTable.Root/Header/ HeaderCell/Body/Row/Cell/ExpandedContent) with arbitrary non-tabular row expansion (R-EXPAND), measured variable row + expanded-row heights, live tail, per-column sort, and a CloudWatch Logs Insights demo (standard + patterns + raw views). Unit + a11y tests and usage docs included. Build/lint/tests green. Draft design-study PR; official Cloudscape API review + design/release sign-off remain human-gated.

Summary
Adds VirtualTable (design-study cell F1-A2): a new, additive, virtualization-first compound-components table that coexists with
Table(not a rewrite). Composition isVirtualTable.Root / Header / HeaderCell / Body / Row / Cell / ExpandedContent, where theBodyrow-template(item, api) => Rowis invoked only for windowed rows.Highlights:
VirtualTable.ExpandedContentrenders content with a different structure from the columns, with measured variable expanded-row heights and a valid grid-child disclosure a11y model.aria-rowcount/rowindex/colcount/colindex), materialised disclosure column, single tab stop +aria-activedescendant, row-granular keyboard.Testing
npm run buildgreen;npm run lintgreen (0 errors); unit + a11y suites green (56/56 across 4 suites:use-virtual-model,use-expansion,virtual-table,virtual-table-a11y). Usednpm install(notnpm ci).Known limitations / follow-ups
build-tools/tasks/docs.js) supports only a single-function default export perindex.tsx; a compound-namespace component cannot be introspected. VirtualTable is temporarily excluded from the documenter glob (clearly commented) and its API is described insrc/virtual-table/USAGE.md— documenter support for compound components is a follow-up.prefer-live-region) on the rawaria-livenode — a follow-up to adopt the internalLiveRegioncomponent.Human-gated (NOT in scope)
Official Cloudscape API review and design/release sign-off. This is one framing/approach cell (F1-A2) of a broader design study; the final API is subject to team review.
