huluTable-dsh-plugin

huluTable drops a full-featured online spreadsheet into the DeepSeek Harness sidebar. No database, no backend server—every record is written straight into the browser's IndexedDB and works out of the box. Its job is simple: let you maintain structured data such as a customer CRM, project board, finance ledger, or attendance log right inside your Harness workflow, without breaking context to open another web app or desktop tool.

The core experience centers on a virtualized grid editor that stays smooth past a hundred thousand rows. Double-click a cell to edit, drag the corner handle to fill an incremental series, and every mutation is undoable at the delta level. On top of the grid you get 18 column types with format validation (phone, email, regex, etc.), frozen columns, linked dropdown selectors, and 30-plus built-in formulas with automatic recalculation. The same table can be viewed as a grid, a Kanban board (grouped by a dropdown column, drag cards to model a CRM funnel), a month calendar (driven by a date column), or a bar / pie / funnel chart. Excel and CSV import-export, one-click JSON backup and restore, per-cell edit history, and inline comments round out the day-to-day collaboration loop.

It is built for individual developers or small teams who already work inside DeepSeek Harness and want a lightweight data workbench: no PostgreSQL to provision, no Nginx to deploy, just browser-local storage that persists across sessions. If you need Harness to double as a quick spreadsheet workspace, huluTable is the plug-and-play table that slot straight in.
