column-filtering

A guide to filtering table columns and deciding whether filtering happens in the browser or on a server. It also covers filter functions, extra filter information, nested rows, and filter controls.

In plain words
What is it for?
Use it to add text, numeric, nested-row, or custom column filters; provide facet-related metadata; and send filter state to a server when the server owns filtering.
Why use it?
It separates filter state, the code that processes rows, and the user interface, reducing mistakes such as combining client and server filtering or using an incompatible accessor.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

column-filtering scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill builds on core, table-features, and client-vs-server. Filtering state, row processing, and filter UI are separate concerns.

Setup

import {
  columnFilteringFeature,
  createFilteredRowModel,
  filterFn_includesString,
  tableFeatures,
} from '@tanstack/table-core'

export const features = tableFeatures({
  columnFilteringFeature,
  filteredRowModel: createFilteredRowModel(),
  filterFns: { includesString: filterFn_includesString },
})

Import individual filterFn_* built-ins and register only those your columns reference by string name or that filterFn: 'auto' should resolve for your data types. The full filterFns registry object still works but bundles every built-in.

Core Patterns

const options = {
  filterFromLeafRows: true,
  maxLeafRowFilterDepth: 2,
}

Use leaf-first filtering only when a parent should survive because a descendant matches.

Common Mistakes

[HIGH] Combining manual and client filtering

Wrong: const options = { manualFiltering: true }

Correct: const options = { manualFiltering: false }

Manual mode returns the pre-filtered model; send filter state to the server instead if it is true.

Source: packages/table-core/src/features/column-filtering/columnFilteringFeature.types.ts

[HIGH] Filtering renderer output

Wrong: helper.accessor(row => ({ label: row.status }), { filterFn: 'includesString' })

Correct: helper.accessor('status', { filterFn: 'includesString' })

Built-in string and numeric filters expect comparable accessor values, not objects or UI nodes.

Source: docs/framework/react/guide/column-filtering.md#filterfns

[HIGH] Ignoring updater-function callbacks

Wrong: onColumnFiltersChange: value => { columnFilters = value as ColumnFiltersState }

Correct: onColumnFiltersChange: updater => { columnFilters = functionalUpdate(updater, columnFilters) }

Controlled callbacks receive either a value or a function of previous state.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

column-filtering is a skill published in the GitHub repository TanStack/table (28,393 stars, last pushed 2d ago), licensed MIT. It adds 48 tokens to every session and 658 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
