Table_CellSelection

Defined in: features/cell-selection/cellSelectionFeature.types.ts:207

Type Parameters#

TFeatures#

TFeatures extends TableFeatures

TData#

TData extends RowData

Properties#

_isSelectingCells#

_isSelectingCells: boolean;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:220

Internal

Whether a drag selection is currently open.

Non-reactive instance data rather than state: only the mouse handlers read it, nothing renders from it, and keeping it out of the slice means a selection persisted mid-drag cannot rehydrate into a stuck drag.

autoResetCellSelection#

autoResetCellSelection: () => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:227

Schedules a cell selection reset after data changes.

Honors autoResetAll and autoResetCellSelection. Called by the core row model; you rarely need to invoke it yourself.

Returns#

void

extendCellSelection#

extendCellSelection: (direction) => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:231

Extends the active range one step in a direction, keeping its anchor fixed.

Parameters#

direction#

CellSelectionDirection

Returns#

void

getCellSelectionBounds#

getCellSelectionBounds: () => CellSelectionBounds[];

Defined in: features/cell-selection/cellSelectionFeature.types.ts:239

Returns the final positive selection as disjoint, inclusive display-order index rectangles after all include and exclude operations are applied.

This is the memoized cache every per-cell read goes through. Ranges whose corners no longer resolve are omitted.

Returns#

CellSelectionBounds[]

getCellSelectionColumnIds#

getCellSelectionColumnIds: () => string[];

Defined in: features/cell-selection/cellSelectionFeature.types.ts:252

Returns the ids of all columns intersected by the selection.

Returns#

string[]

getCellSelectionColumnIndexes#

getCellSelectionColumnIndexes: () => Record<string, number>;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:261

Internal

Returns a column id to display-index map for the current column order.

Registered so the lookup stays memoized even when columnOrderingFeature is absent, since its getColumnIndexes static rebuilds on every call.

Returns#

Record<string, number>

getCellSelectionMergeBounds#

getCellSelectionMergeBounds: () => CellSelectionBounds[];

Defined in: features/cell-selection/cellSelectionFeature.types.ts:248

Returns the merged-cell rectangles of the rendered rows in selection's display-order index space, or an empty array when cellSpanningFeature is not registered.

Selection rectangles expand to fully enclose these, so a merged cell is always entirely selected or entirely unselected.

Returns#

CellSelectionBounds[]

getCellSelectionRowIds#

getCellSelectionRowIds: () => string[];

Defined in: features/cell-selection/cellSelectionFeature.types.ts:265

Returns the ids of all rows intersected by the selection.

Returns#

string[]

getFocusedCell#

getFocusedCell: () =>
  | Cell<TFeatures, TData, any>
  | undefined;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:270

Returns the active cell, i.e. the anchor of the most recent operation. An exclusion's active cell is focused even though it is not selected.

Returns#

| Cell<TFeatures, TData, any> | undefined

getSelectedCellCount#

getSelectedCellCount: () => number;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:277

Returns the number of selected cells.

Computed with rectangle arithmetic unless a per-cell enableCellSelection predicate requires enumeration.

Returns#

number

getSelectedCellIds#

getSelectedCellIds: () => string[];

Defined in: features/cell-selection/cellSelectionFeature.types.ts:284

Returns the unique ids of all selected cells, in row-major order.

This expands the selection, so it costs one pass over the selected area. It is memoized and never runs unless called.

Returns#

string[]

getSelectedCellRangesData#

getSelectedCellRangesData: () => unknown[][][];

Defined in: features/cell-selection/cellSelectionFeature.types.ts:292

Returns each final positive selection region's values as a row-major grid.

Indexed as [regionIndex][rowIndex][columnIndex]. Serializing this to clipboard text is left to userland, since the delimiter, the null representation, and any quoting rules are application decisions.

Returns#

unknown[][][]

moveCellSelection#

moveCellSelection: (direction) => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:297

Moves the selection one step in a direction, collapsing it to a single cell. Columns that cannot be selected are skipped over.

Parameters#

direction#

CellSelectionDirection

Returns#

void

resetCellSelection#

resetCellSelection: (defaultState?) => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:303

Resets cellSelection to initialState.cellSelection.

Pass true to ignore initial state and reset to an empty selection.

Parameters#

defaultState?#

boolean

Returns#

void

selectAllCells#

selectAllCells: () => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:307

Selects every selectable cell in the table as one range.

Returns#

void

selectCellRange#

selectCellRange: (range, opts?) => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:311

Selects a rectangle using the requested replace/include/exclude mode.

Parameters#

range#

CellSelectionRange

opts?#

SelectCellRangeOptions

Returns#

void

setCellSelection#

setCellSelection: (updater) => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:318

Updates cell selection state with a next value or updater function.

Parameters#

updater#

Updater<CellSelectionState>

Returns#

void

setFocusedCell#

setFocusedCell: (rowId, columnId) => void;

Defined in: features/cell-selection/cellSelectionFeature.types.ts:322

Collapses the selection to a single cell at the given coordinates.

Parameters#

rowId#

string

columnId#

string

Returns#

void
