Composable editable spreadsheet grid: a headless engine (focus, selection, edit lifecycle, undo/redo, clipboard — all rowId-addressed so sort/filter work while editing) + a skin composed with DataTableRoot and the virtualized body. Keyboard cell nav, drag range-select with edge auto-scroll, quote-aware TSV copy/cut/paste with one-to-many tiling, fill handle, drag-move, dynamic columns, row drag-to-reorder, selection status bar, cross-highlight, and text/number/checkbox/date/select/combobox cells. Virtualized to 100k+ rows.
