Tables are essential for presenting large volumes of data in a structured and easily digestible format. When working with data in React applications, the React-Table library stands out as a powerful tool for creating dynamic tables.

In this article, we will explore how to configure React-Table hooks to sort data by default, enhancing user experience and ensuring that your data presentation is both efficient and user-friendly. Whether you’re displaying product listings, user information, or any other type of data, mastering sorting with React-Table will elevate your application’s functionality.

Understanding React-Table

React-Table is a lightweight and flexible library that allows developers to create fully customizable tables. It provides a set of hooks that make it easy to manage table state, including sorting, filtering, and pagination. The library is designed to be easy to use while offering a high degree of customization.

To get started with React-Table, you need to install the library and set up your project. You can easily do this using npm:

npm install react-table

Once installed, you can import the necessary hooks and components from the library to create your table. The core functionality of React-Table revolves around the use of hooks like useTable, useSortBy, and others, which allow you to define the structure and behavior of your table.

Setting Up a Basic Table

Before diving into sorting, let’s create a basic table structure using React-Table. This will serve as the foundation for implementing sorting functionality.

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;

This code sets up a simple table component that accepts columns and data as props. The useTable hook is used to create the table instance, which provides various properties and methods to manage the table’s behavior. The component renders the table structure, including headers and body rows.

Now that we have a basic table set up, let’s move on to implementing sorting.

Implementing Sorting with React-Table

Sorting is a crucial feature for any data table. With React-Table, you can easily add sorting capabilities using the useSortBy hook. Below is an example of how to implement sorting in your table.

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

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

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                {column.render('Header')}
                <span>
                  {column.isSorted ? (column.isSortedDesc ? ' 🔽' : ' 🔼') : ''}
                </span>
              </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;

In this code, we import the useSortBy hook alongside useTable. By including useSortBy in the hook configuration, we enable sorting functionality. The getSortByToggleProps method is used to attach sorting behavior to the header cells. Additionally, we provide visual indicators (arrows) to show the sorting direction.

When a user clicks on a column header, the table will sort the data based on that column, improving the overall data navigation experience.

Customizing Default Sorting

React-Table allows you to set default sorting when the table first loads. This can be particularly useful when you want to present data in a specific order right from the start. You can achieve this by passing a defaultSorted property in the table configuration.

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

const TableComponent = ({ columns, data }) => {
  const { getTableProps, getTableBodyProps, headerGroups, rows, prepareRow } = useTable(
    { columns, data, initialState: { sortBy: [{ id: 'column_id', desc: false }] } },
    useSortBy
  );

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                {column.render('Header')}
                <span>
                  {column.isSorted ? (column.isSortedDesc ? ' 🔽' : ' 🔼') : ''}
                </span>
              </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;

In this example, we set the initialState property with a sortBy array. The id corresponds to the column you want to sort by default, and desc indicates whether the sorting should be descending or ascending. This approach allows you to control how the data is displayed when the table is first rendered, providing a better user experience.

Conclusion

Sorting data in a React application can significantly enhance the user experience, especially when dealing with large datasets. The React-Table library provides a robust and flexible solution for creating sortable tables with minimal effort. By utilizing hooks like useTable and useSortBy, you can easily implement sorting features, customize default sorting, and create a user-friendly interface. With these tools at your disposal, you can ensure that your data is presented in an organized and efficient manner, making it easier for users to navigate and analyze the information.
