Source Code ↗

CellStatus

type CellStatus = "valid" | "invalid" | "empty"

CellState

Each editable cell keeps raw, resolved value, and status separate so a pasted-but-unmatched value stays visible (and correctable).

interface CellState<T> {
  raw: string
  value: T | null
  status: CellStatus
  /** Tooltip when invalid. */
  error?: string
}

CellPosition

Address by row id and column id: not display index: so focus/selection survive filter/sort/reorder.

interface CellPosition {
  rowId: string
  columnId: string
}

CopiedRange

Marching-ants copy outline, captured by identity (Set membership + edge ids).

interface CopiedRange {
  rowIds: Set<string>
  firstRowId: string
  lastRowId: string
  columnIds: Set<string>
  firstColumnId: string
  lastColumnId: string
}

SelectionBounds

Inclusive selection rectangle in display space (post filter/sort indices).

interface SelectionBounds {
  minRow: number
  maxRow: number
  minColIndex: number
  maxColIndex: number
}

GridRow

interface GridRow {
  id: string
  [columnId: string]: CellState<string> | string
}
