React Table useGlobalFilter with two columns

This week I needed to filter a table made with React Table. React table is great for its extensibility and so has hooks for this: useFilters and useGlobalFilter. useFilter is for filtering by an individual column and useGlobalFilter for filtering by content in any column.

However I needed to filter two columns by a single input. My table is for ingredients and has columns for: code, name, price per unit, supplier, etc. I need to filter by name and code. I couldn't use useFilters as that would do an intersection (i.e. the search query would need to be in both the code and name row).

Thankfully, it's possible to do this with useGlobalFilter.

import { 
    ..., 
    useGlobalFilter,
} from 'react-table'

...

const {
    ...,
    setGlobalFilter,
} = useTable(
    {
        ...
    },
    ...
    useGlobalFilter,
);

Awesome, by using setGlobalFilter we can now filter by the content in any column. To restrict which columns we filter we'll specify a custom globalFilter function.

import {
    ...
    useGlobalFilter,
    Row, // Typescript
    IdType, // Typescript
}
import React, { ..., useCallback } = 'react'

...

const ourGlobalFilterFunction = useCallback(
    // This is Typescript if you're using JS remove the types (e.g. :string)
    (rows: Row<T>[], ids: IdType<T>[], query: string) => {
        return rows.filter((row) => 
            row.values['code'].includes(query) ||
            row.values['name'].includes(query)
        );
    },
    [],
);

const {
    ...
    setGlobalFilter,
} = useTable(
    {
        globalFilter: ourGlobalFilterFunction
    },
    ...
    useGlobalFilter,
);
Enter fullscreen mode Exit fullscreen mode

However, in my case this is inside a Table component which I use in a couple of places, so let's make ourGlobalFilterFunction take arbitrary column names for filtering. We'll also pass the filter query as a prop to Table.

interface TableProps {
    filters: string[];
    filter: string;
}

const Table: React.FC<TableProps> = ({
    filters,
    filter,
}): React.ReactComponent => {

    const ourGlobalFilterFunction = useCallback(
        // This is Typescript if you're using JS remove the types (e.g. :string)
        (rows: Row<T>[], ids: IdType<T>[], query: string) => {
            return rows.filter((row) => 
                for (const filter of filters) {
                    return row.values[filter].includes(query)
                }
            );
        },
        [filters],
    );

    const {
      ...
      setGlobalFilter,
    } = useTable(
        {
            globalFilter: ourGlobalFilterFunction
        },
        ...
        useGlobalFilter,
    );

    useEffect(() => {
        setGlobalFilter(filter) // Set the Global Filter to the filter prop.
    }, [filter, setGlobalFilter]);

    return (
        ...
    );
}

Finally, I'd like this to do fuzzy text filtering. We'll use the match-sorter library for this

npm install match-sorter
Enter fullscreen mode Exit fullscreen mode
import { matchSorter } from 'match-sorter';

...

const globalFilter = useCallback(
    (rows: Row<T>[], ids: IdType<T>[], query: string) => {
        return matchSorter(rows, query, {
            keys: filters.map((columnName) => `values.${columnName}`),
        });
    },
    [filters],
);
Enter fullscreen mode Exit fullscreen mode
