Research type: Sourced diagnostic guide
Method: Primary documentation plus two selected public developer reports, dated 2021 and 2026, and two local network-disabled Chrome runs on an owned 48-row fixture v1.0.1. The fixture uses a 960 × 560 inner panel and records 20 states with viewport/full-page captures in each run. Selected images show position-specific row spans; independent visual adjudication records their exact visible label ranges. This is not a commercial screenshot-app benchmark. Sources checked September 19–20, 2026.

A full-page screenshot can include the footer and still miss most of a table.

If the table scrolls inside its own panel, capturing the surrounding page does not establish that you captured every row. Before changing tools, identify which part of the interface actually moves. A dashboard can contain several independent scroll areas, each showing a different slice of its content.

This confusion appears in two specific public reports. On April 15, 2021, a developer asked why [html2canvas captured only the visible part of a scrolling div](https://stackoverflow.com/questions/67103097/html2canvas-render-only-the-visible-part-of-div-element). On January 7, 2026, another reported the same expectation gap with [Playwright 1.57.0 element
