Accessibility

Built to WCAG 2.2 level AA. Every operation is reachable without a pointer, including resizing and reordering a column, which have key bindings and column-menu items rather than depending on a drag. The grid reports itself as grid or treegrid following its configuration; rows and cells carry their position in the dataset rather than in the rendered window, so a reader on row 500,000 is told so; and rows in a hierarchy carry their position among their siblings, which a reader cannot count for itself when most of a branch was never rendered.

Focus is real focus rather than aria-activedescendant, and survives row recycling. Sorting, filtering, selection, grouping, expanding, paging, undo, paste and a refused edit are all announced. In Windows High Contrast Mode state is translated into borders and system colours instead of tints. No information is carried by hue alone.

The full keyboard map, the screen reader support statement and the known limits, including the drag-only pivot zones, are in the guide.
