column-visibility

name	column-visibility
description	Hide columns with columnVisibilityFeature while rendering visibility-aware header, column, and cell collections. Load when hidden columns remain in the DOM, false-versus-absent state is confused, or enableHiding is misunderstood.

This skill builds on core and table-features. Visibility state changes visibility-aware models; it never removes the column definition.

Setup

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

export const features = tableFeatures({ columnVisibilityFeature })
export const initialState = { columnVisibility: { internalId: false } }

Core Patterns

const headers = table.getHeaderGroups()
const cells = row.getVisibleCells()
const toggles = table
  .getAllLeafColumns()
  .filter((column) => column.getCanHide())

Use all-column APIs for controls and visible APIs for rendered table content.

Common Mistakes

[HIGH] Rendering hidden cells anyway

Wrong: row.getAllCells().map(renderCell)

Correct: row.getVisibleCells().map(renderCell)

All-cell APIs intentionally include hidden columns.

[HIGH] Treating absence as hidden

Wrong: const hidden = !columnVisibility[column.id]

Correct: const hidden = columnVisibility[column.id] === false

Only explicit false hides a column; an absent entry is visible.

[MEDIUM] Treating enableHiding as visibility

Wrong: helper.accessor('id', { enableHiding: false })

Correct: const initialState = { columnVisibility: { id: false } }

enableHiding controls whether hiding is allowed; visibility belongs in table state.
