tanstack-table-core-cell-spanning

This skill builds on core and table-features. Cell spanning is stateless and fully derived: a memoized table-level span index is rebuilt from the rows that are actually rendered, and per-cell reads are O(1) lookups against it. Sorting, filtering, pagination, and row pinning only change adjacency; spans follow automatically and never persist.

Setup

import { cellSpanningFeature, tableFeatures } from '@tanstack/table-core'

export const features = tableFeatures({ cellSpanningFeature })

Core Patterns

Opt columns into value-based row spanning
