Filter Functions
----------------

The following filter functions are built-in to the table core:

includesString
- Case-insensitive string inclusion
includesStringSensitive
- Case-sensitive string inclusion
equalsString
- Case-insensitive string equality
equalsStringSensitive
- Case-sensitive string equality
arrIncludes
- Item inclusion within an array
arrIncludesAll
- All items included in an array
arrIncludesSome
- Some items included in an array
equals
- Object/referential equality Object.is/===
weakEquals
- Weak object/referential equality ==
inNumberRange
- Number range inclusion

Every filter function receives:

The row to filter
The columnId to use to retrieve the row's value
The filter value

and should return true if the row should be included in the filtered rows, and false if it should be removed.

This is the type signature for every filter function:

tsx

export type FilterFn<TData extends AnyData> = {
  (
    row: Row<TData>,
    columnId: string,
    filterValue: any,
    addMeta: (meta: any) => void
  ): boolean
  resolveFilterValue?: TransformFilterValueFn<TData>
  autoRemove?: ColumnFilterAutoRemoveTestFn<TData>
  addMeta?: (meta?: any) => void
}

export type TransformFilterValueFn<TData extends AnyData> = (
  value: any,
  column?: Column<TData>
) => unknown

export type ColumnFilterAutoRemoveTestFn<TData extends AnyData> = (
  value: any,
  column?: Column<TData>
) => boolean

export type CustomFilterFns<TData extends AnyData> = Record<
  string,
  FilterFn<TData>
>


export type FilterFn<TData extends AnyData> = {
  (
    row: Row<TData>,
    columnId: string,
    filterValue: any,
    addMeta: (meta: any) => void
  ): boolean
  resolveFilterValue?: TransformFilterValueFn<TData>
  autoRemove?: ColumnFilterAutoRemoveTestFn<TData>
  addMeta?: (meta?: any) => void
}

export type TransformFilterValueFn<TData extends AnyData> = (
  value: any,
  column?: Column<TData>
) => unknown

export type ColumnFilterAutoRemoveTestFn<TData extends AnyData> = (
  value: any,
  column?: Column<TData>
) => boolean

export type CustomFilterFns<TData extends AnyData> = Record<
  string,
  FilterFn<TData>
>

### filterFn.resolveFilterValue

This optional "hanging" method on any given filterFn allows the filter function to transform/sanitize/format the filter value before it is passed to the filter function.

### filterFn.autoRemove

This optional "hanging" method on any given filterFn is passed a filter value and expected to return true if the filter value should be removed from the filter state. eg. Some boolean-style filters may want to remove the filter value from the table state if the filter value is set to false.

#### Using Filter Functions

Filter functions can be used/referenced/defined by passing the following to columnDefinition.filterFn:

A string that references a built-in filter function
A function directly provided to the columnDefinition.filterFn option

The final list of filter functions available for the columnDef.filterFn option use the following type:

tsx

export type FilterFnOption<TData extends AnyData> =
  | 'auto'
  | BuiltInFilterFn
  | FilterFn<TData>


export type FilterFnOption<TData extends AnyData> =
  | 'auto'
  | BuiltInFilterFn
  | FilterFn<TData>

#### Filter Meta

Filtering data can often expose additional information about the data that can be used to aid other future operations on the same data. A good example of this concept is a ranking-system like that of match-sorter that simultaneously ranks, filters and sorts data. While utilities like match-sorter make a lot of sense for single-dimensional filter+sort tasks, the decoupled filtering/sorting architecture of building a table makes them very difficult and slow to use.

To make a ranking/filtering/sorting system work with tables, filterFns can optionally mark results with a filter meta value that can be used later to sort/group/etc the data to your liking. This is done by calling the addMeta function supplied to your custom filterFn.

Below is an example using our own match-sorter-utils package (a utility fork of match-sorter) to rank, filter, and sort the data

tsx

import { sortingFns } from '@tanstack/react-table'

import { rankItem, compareItems } from '@tanstack/match-sorter-utils'

const fuzzyFilter = (row, columnId, value, addMeta) => {
  // Rank the item
  const itemRank = rankItem(row.getValue(columnId), value)

  // Store the ranking info
  addMeta(itemRank)

  // Return if the item should be filtered in/out
  return itemRank.passed
}

const fuzzySort = (rowA, rowB, columnId) => {
  let dir = 0

  // Only sort by rank if the column has ranking information
  if (rowA.columnFiltersMeta[columnId]) {
    dir = compareItems(
      rowA.columnFiltersMeta[columnId]!,
      rowB.columnFiltersMeta[columnId]!
    )
  }

  // Provide an alphanumeric fallback for when the item ranks are equal
  return dir === 0 ? sortingFns.alphanumeric(rowA, rowB, columnId) : dir
}


import { sortingFns } from '@tanstack/react-table'

import { rankItem, compareItems } from '@tanstack/match-sorter-utils'

const fuzzyFilter = (row, columnId, value, addMeta) => {
  // Rank the item
  const itemRank = rankItem(row.getValue(columnId), value)

  // Store the ranking info
  addMeta(itemRank)

  // Return if the item should be filtered in/out
  return itemRank.passed
}

const fuzzySort = (rowA, rowB, columnId) => {
  let dir = 0

  // Only sort by rank if the column has ranking information
  if (rowA.columnFiltersMeta[columnId]) {
    dir = compareItems(
      rowA.columnFiltersMeta[columnId]!,
      rowB.columnFiltersMeta[columnId]!
    )
  }

  // Provide an alphanumeric fallback for when the item ranks are equal
  return dir === 0 ? sortingFns.alphanumeric(rowA, rowB, columnId) : dir
}

A function that sets the current filter value for the column. You can pass it a value or an updater function for immutability-safe operations on existing values.

### getAutoFilterFn

tsx

getAutoFilterFn: (columnId: string) => FilterFn<TData> | undefined


getAutoFilterFn: (columnId: string) => FilterFn<TData> | undefined

Returns an automatically calculated filter function for the column based off of the columns first known value.

getFilterFn: (columnId: string) => FilterFn<TData> | undefined

Returns the filter function (either user-defined or automatic, depending on configuration) for the columnId specified.

Row API
------- ### columnFilters

tsx

columnFilters: Record<string, boolean>


columnFilters: Record<string, boolean>

The column filters map for the row. This object tracks whether a row is passing/failing specific filters by their column ID.

### columnFiltersMeta

tsx

columnFiltersMeta: Record<string, any>


columnFiltersMeta: Record<string, any>

The column filters meta map for the row. This object tracks any filter meta for a row as optionally provided during the filtering process.

Table Options
------------- ### filterFns

tsx

filterFns?: Record<string, FilterFn>


filterFns?: Record<string, FilterFn>

This option allows you to define custom filter functions that can be referenced in a column's filterFn option by their key. Example:

tsx

declare module '@tanstack/[adapter]-table' {
  interface FilterFns {
    myCustomFilter: FilterFn<unknown>
  }
}

const column = columnHelper.data('key', {
  filterFn: 'myCustomFilter',
})

const table = useReactTable({
  columns: [column],
  filterFns: {
    myCustomFilter: (rows, columnIds, filterValue) => {
      // return the filtered rows
    },
  },
})


declare module '@tanstack/[adapter]-table' {
  interface FilterFns {
    myCustomFilter: FilterFn<unknown>
  }
}

const column = columnHelper.data('key', {
  filterFn: 'myCustomFilter',
})

const table = useReactTable({
  columns: [column],
  filterFns: {
    myCustomFilter: (rows, columnIds, filterValue) => {
      // return the filtered rows
    },
  },
})

### filterFromLeafRows

tsx

filterFromLeafRows?: boolean


filterFromLeafRows?: boolean

By default, filtering is done from parent rows down (so if a parent row is filtered out, all of its children will be filtered out as well). Setting this option to true will cause filtering to be done from leaf rows up (which means parent rows will be included so long as one of their child or grand-child rows is also included).

### maxLeafRowFilterDepth

tsx

maxLeafRowFilterDepth?: number


maxLeafRowFilterDepth?: number

By default, filtering is done for all rows (max depth of 100), no matter if they are root level parent rows or the child leaf rows of a parent row. Setting this option to 0 will cause filtering to only be applied to the root level parent rows, with all sub-rows remaining unfiltered. Similarly, setting this option to 1 will cause filtering to only be applied to child leaf rows 1 level deep, and so on.

This is useful for situations where you want a row's entire child hierarchy to be visible regardless of the applied filter.

### enableFilters

tsx

enableFilters?: boolean


enableFilters?: boolean

Enables/disables all filters for the table.

### manualFiltering

tsx

manualFiltering?: boolean


manualFiltering?: boolean

Disables the getFilteredRowModel from being used to filter data. This may be useful if your table needs to dynamically support both client-side and server-side filtering.

### onColumnFiltersChange

tsx

onColumnFiltersChange?: OnChangeFn<ColumnFiltersState>


onColumnFiltersChange?: OnChangeFn<ColumnFiltersState>

If provided, this function will be called with an updaterFn when state.columnFilters changes. This overrides the default internal state management, so you will need to persist the state change either fully or partially outside of the table.

### enableColumnFilters

tsx

enableColumnFilters?: boolean


enableColumnFilters?: boolean

Enables/disables all column filters for the table.

### getFilteredRowModel

tsx

getFilteredRowModel?: (
  table: Table<TData>
) => () => RowModel<TData>


getFilteredRowModel?: (
  table: Table<TData>
) => () => RowModel<TData>

If provided, this function is called once per table and should return a new function which will calculate and return the row model for the table when it's filtered.

For server-side filtering, this function is unnecessary and can be ignored since the server should already return the filtered row model.
For client-side filtering, this function is required. A default implementation is provided via any table adapter's { getFilteredRowModel } export.

Example:

tsx

import { getFilteredRowModel } from '@tanstack/[adapter]-table'


  getFilteredRowModel: getFilteredRowModel(),
})


import { getFilteredRowModel } from '@tanstack/[adapter]-table'


  getFilteredRowModel: getFilteredRowModel(),
})

Table API
--------- ### setColumnFilters

tsx

setColumnFilters: (updater: Updater<ColumnFiltersState>) => void


setColumnFilters: (updater: Updater<ColumnFiltersState>) => void

Sets or updates the state.columnFilters state.

### resetColumnFilters

tsx

resetColumnFilters: (defaultState?: boolean) => void


resetColumnFilters: (defaultState?: boolean) => void

Resets the columnFilters state to initialState.columnFilters, or true can be passed to force a default blank state reset to [].

### getPreFilteredRowModel

tsx

getPreFilteredRowModel: () => RowModel<TData>


getPreFilteredRowModel: () => RowModel<TData>

Returns the row model for the table before any column filtering has been applied.

### getFilteredRowModel

tsx

getFilteredRowModel: () => RowModel<TData>


getFilteredRowModel: () => RowModel<TData>

Returns the row model for the table after column filtering has been applied.
