@gridkitjs/core v0.10.0

Minor Changes#

• bedd76c: virtualized: renders only the rows near the current scroll position rather than every row at once, for a dataset too large to mount in full. Requires height to be set — a body with no bounded height has no viewport to window rows against, and a dev-time console.error fires if virtualized is on without it.

  <DataGridComponent
    columns={columns}
    dataSource={rows}
    height={400}
    virtualized
  />

  Row height is measured per row rather than assumed uniform, so .is-wrapped cells and group header/summary rows (which differ in height from data rows) lay out correctly. Two new props tune it: overscan (rows rendered outside the visible range on each side, default 4) and estimatedRowHeight (the assumed height for a row never yet measured, default 40) — both meaningful only with virtualized on.

  scrollToRow and keyboard navigation (arrow keys, Home/End, Ctrl+Home/Ctrl+End) both work correctly when their target row isn't currently mounted: they scroll it into range first, using measured heights where known, then correct the exact position once it mounts and is measured.

  Fully orthogonal to paginated and groupBy — combinable with either, though virtualizing an already-small paginated page is low-value.

  @gridkitjs/core gains visibleRange (plus its RowHeights/VisibleRange types) — the pure range math virtualized is built on. Not something most consumers need directly; it's exported for the same reason paginateRows is.
