Range Grid

A grid with 2-D rectangular cell selection — the spreadsheet model. An anchor and a focus cell define a selected rectangle: Shift+Arrow extends it, a plain Arrow collapses it, and Ctrl/Cmd+A selects all. Cells expose `aria-selected` and 1-based `aria-rowindex`/`aria-colindex`; the grid exposes the full row and column counts.

  • Axe
  • Name
  • Roving
  • Focus
