Function: createColumnHelper()#

function createColumnHelper<TFeatures, TData>(): ColumnHelper<TFeatures, TData>;

Defined in: helpers/columnHelper.ts:99

Creates helper functions for authoring column definitions with stronger value inference.

accessor infers TValue from an accessor key or accessor function, display creates non-data columns, group creates parent columns, and columns preserves tuple-level value types for arrays. At runtime these helpers only return column definition objects.

Type Parameters#

TFeatures#

TFeatures extends TableFeatures

TData#

TData extends RowData

Returns#

ColumnHelper\<`TFeatures`, `TData`\>

Example#

const helper = createColumnHelper<typeof features, Person>() // features is the result of `tableFeatures({})` helper
const columns = [
 helper.display({ id: 'actions', header: 'Actions' }),
 helper.accessor('firstName', {}),
 helper.accessor((row) => row.lastName, { id: 'lastName' }),
]
