Responsive table: headers, scrolling and selection

Original local draft fixture. Synthetic data. No external requests or dependencies.

Focus: none recorded.

Fixture list and exact steps

  1. T10-A — narrow and scroll. Activate “Narrow to 320 px”, then “Focus scroll region”. Press ArrowRight four times, then ArrowDown four times. Record scrollLeft, scrollTop and header offset in diagnostics; inspect the column labels. “Wide layout” restores the container.
  2. T10-B — row selection. Activate “Reset fixture”. Tab from “Focus scroll region” into the table region and onward to “Select Cedar”. Press Space. Record checkbox state, the visible “Selected” label and selectedRows. Press Space again to deselect.
  3. T10-C — header relationships. Inspect the native table: caption, four column headers and each row’s named header. Record headerScope and rowHeaderCount. Inspect the last row after scrolling. No screen-reader result is implied.
  4. T10-D — bounds. Activate “Scroll to bottom right”, inspect sticky header and overflow bounds, then “Reset fixture”. Record both states. This button is a programmatic-scroll check; it is not evidence of touch scrolling.
