opt-datagrid

Operational grid chrome with column visibility, density, full screen, and a locked identity column wired to the live DataGrid.

A campaign workspace with editable grids, saved views, filtering, sorting, grouping, a status board, record details, bulk actions, undo/redo, and local persistence.

Headless remote datasource with placeholder rows, window loading, and batched saves.

Performance preset for large datasets with stable identity and cached values.

Read-only monitoring grid with status badges and metric-heavy columns.

A table a real model writes while you watch: YAML becomes patches, changes wait for review, edits are never overwritten, and formulas, sorting and per-row AI columns take one line.

A monthly ledger workspace. Compound entries expand under their row into one keyboard grid with the parent, amount cells take separators and calculations, closed splits keep their drafts, and saving jumps to whatever blocks it. Deposits and credits show in red, payments and debits in blue, and negative amounts in red parentheses.

Double-entry journal grid wiring one editor per column — date, select, number, checkbox, textarea, and a custom split editor — with keyboard flow, fill handle, undo/redo, and commit-time validation.

Starter spreadsheet grid with editable columns and commit feedback.

Row evaluation with bounded concurrency, cancellation, stale results after editing, and review filtering with mock and authenticated live Jev modes, saved results, and detailed distributions.

Evaluate selected rows, switch local rule providers and criteria, and recover from simulated rate limits, timeouts, save failures and cancellation without AI calls.
