## About

# Extract Table Pagination

## When to invoke

When the user task involves reading structured data from an HTML table — the page either shows a `` element, or a `role="table"` ARIA structure. If the table is paginated, the skill walks pages via a "next" link/button until either the next link is absent, the row count stops growing, or a configurable `max_pages` is reached.

The matcher gives this a high score when the DOM summary contains ``-grid layout (card grid, masonry, etc.) — use the future `extract-card-grid` skill, or vision fallback.
- The table is virtualized (only renders visible rows on scroll, e.g., AG Grid, MUI DataGrid). Use `handle-infinite-scroll` with row-extraction inside the scroll loop instead.
- The "table" is actually a layout `` from 2003-era HTML (no ``, no semantic structure). The extractor will produce noisy results; better to extract by text-selector and structure manually.

## Known failures

- **Virtualized tables (~5% of modern web apps):** only the visible rows are in the DOM at any time. The extractor returns just those. Workaround: combine with `handle-infinite-scroll` or scroll-and-extract.
- **Tables with rowspan/colspan (~3%):** the naive header-zip extractor mis-aligns columns. Vision fallback handles for now; v0.2.0 will support `extract_table mode="rowspan-aware"`.
- **No ``, no `` (~5% of legacy sites):** the extractor uses the first row as headers; if that row is data, the first record is lost. Workaround: pass `headers=[...]` arg (planned v0.2.0).
- **Server-side-rendered "infinite scroll" disguised as pagination:** the next-page link returns the SAME rows on click. Detection logic in `pagination-next-page` aborts when row hashes match.

## Example usage

```
Agent task: "Get the latest cs.AI papers from arxiv."
→ invoke_skill("verify-page-loaded") → success
→ invoke_skill("extract-table-pagination") → success, $rows_page_1 = [{title, authors, abstract}, ...]
→ agent inspects $rows_page_1 and reports
```

## Related skills

- `verify-page-loaded` — run first; tables on slow-rendering pages need readiness check
- `pagination-next-page` — chain to walk multiple pages
- `handle-infinite-scroll` — alternative when content lazy-loads instead of paginating
- `dismiss-cookie-banner` — usually run before any extraction
