The react-table library has become a go-to tool for developers looking to create dynamic and efficient tables in React applications. With its robust features and flexibility, it allows for easy customization, including sorting.

In this article, we will dive into the intricacies of custom sorting using the react-table library. Whether you’re managing a simple dataset or a more complex table, understanding how to implement custom sorting can significantly enhance user experience and data presentation. So, let’s roll up our sleeves and explore how to make this powerful library work for you!

Understanding React-Table

Before we jump into custom sorting, let’s take a moment to understand what react-table is and why it’s widely used. React-table is a lightweight, fast, and extendable library that enables developers to create tables with sorting, filtering, and pagination capabilities. Its headless design allows for complete control over the UI and the data it displays. This flexibility is what makes it a favorite among developers.

The react-table library uses hooks, making it easy to integrate into functional components. It provides a straightforward API for adding features like sorting, which we’ll focus on in this article. By leveraging the power of hooks, you can create a table that not only displays data but also allows users to interact with it seamlessly.

Setting Up React-Table

To get started with react-table, you first need to install it in your React project. You can do this using npm or yarn. Open your terminal and run the following command:

npm install react-table

or

yarn add react-table

Once installed, you can import the necessary hooks and components from the react-table library. Here’s a basic setup to create a simple table:

import React from 'react';
import { useTable } from 'react-table';

const TableComponent = ({ columns, data }) => {
    const {
        getTableProps,
        getTableBodyProps,
        headerGroups,
        rows,
        prepareRow,
    } = useTable({ columns, data });

    return (
        <table {...getTableProps()}>
            <thead>
                {headerGroups.map(headerGroup => (
                    <tr {...headerGroup.getHeaderGroupProps()}>
                        {headerGroup.headers.map(column => (
                            <th {...column.getHeaderProps()}>{column.render('Header')}</th>
                        ))}
                    </tr>
                ))}
            </thead>
            <tbody {...getTableBodyProps()}>
                {rows.map(row => {
                    prepareRow(row);
                    return (
                        <tr {...row.getRowProps()}>
                            {row.cells.map(cell => (
                                <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
                            ))}
                        </tr>
                    );
                })}
            </tbody>
        </table>
    );
};

export default TableComponent;

Output:

A basic table structure using react-table

In this setup, we define a functional component called TableComponent. We use the useTable hook to create a table instance, which provides various props and methods to manage the table’s behavior. The structure includes a table header and body, where we render the data dynamically.

Implementing Custom Sorting

Now that we have a basic table, let’s implement custom sorting. React-table provides built-in sorting capabilities, but we can enhance it by creating our own sorting logic. This allows us to sort data based on custom criteria, which can be particularly useful for complex datasets.

First, let’s modify our TableComponent to include sorting functionality. We will define a custom sorting function and apply it to our table.

const customSort = (rowA, rowB, columnId) => {
    const a = rowA.values[columnId];
    const b = rowB.values[columnId];
    return a > b ? 1 : -1;
};

const TableComponent = ({ columns, data }) => {
    const {
        getTableProps,
        getTableBodyProps,
        headerGroups,
        rows,
        prepareRow,
    } = useTable({
        columns,
        data,
        manualSortBy: true,
        getSortByToggleProps: (column) => ({
            onClick: () => {
                const sortDirection = column.isSortedDesc ? 'asc' : 'desc';
                column.toggleSortBy(sortDirection);
            },
        }),
        sortTypes: {
            custom: customSort,
        },
    });

    return (
        <table {...getTableProps()}>
            <thead>
                {headerGroups.map(headerGroup => (
                    <tr {...headerGroup.getHeaderGroupProps()}>
                        {headerGroup.headers.map(column => (
                            <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                                {column.render('Header')}
                                {column.isSorted ? (column.isSortedDesc ? ' 🔽' : ' 🔼') : ''}
                            </th>
                        ))}
                    </tr>
                ))}
            </thead>
            <tbody {...getTableBodyProps()}>
                {rows.map(row => {
                    prepareRow(row);
                    return (
                        <tr {...row.getRowProps()}>
                            {row.cells.map(cell => (
                                <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
                            ))}
                        </tr>
                    );
                })}
            </tbody>
        </table>
    );
};

Output:

Custom sorting functionality added to the table

In this code, we define a customSort function that compares two rows based on a specified column. We then integrate this sorting logic into the useTable hook by setting manualSortBy to true and specifying our custom sort type. The getSortByToggleProps function allows us to toggle sorting when a column header is clicked, providing visual feedback to users.

Conclusion

Custom sorting in the react-table library is a powerful feature that can significantly improve the usability of your tables. By leveraging the flexibility of this library, developers can create tables that not only display data but also allow users to interact with it in meaningful ways. Whether you’re working with simple datasets or complex information, understanding how to implement custom sorting will enhance your React applications. Now that you have the tools and knowledge, it’s time to put them into practice and create dynamic, user-friendly tables!
