Adjust Row Height in React Table: A Step-by-Step Guide (2026)

React Table is a popular and powerful library for displaying data in a tabular format in React applications. However, its default styling might not fit every design requirement, especially when you want to display a specific number of rows, such as fitting 20 rows on the screen at once. This tutorial will guide you through the steps to customize the row height in a React Table with checkboxes, ensuring a compact and efficient layout.

Key Takeaways

• Learn to customize row height in React Table for better layout control.
• Understand how to use CSS for styling table components.
• Implement checkbox functionality efficiently in React Table.
• Explore common pitfalls and how to troubleshoot them.

In this tutorial, we will explore how to adjust the row height in your React Table setup. This is particularly useful when you want your table to display a fixed number of rows without scrolling. We will achieve this by applying custom CSS styles and ensuring that the table remains responsive and visually appealing.

Prerequisites

• Basic understanding of React and JavaScript.
• Familiarity with CSS for styling components.
• Node.js and npm installed on your system.

Step 1: Set Up Your React Project

If you haven't already set up a React project, you can do so using Create React App. Open your terminal and run:

npx create-react-app react-table-custom-height

Navigate to the project directory:

cd react-table-custom-height

Step 2: Install React Table

Next, you'll need to install the React Table library. This can be done by running:

npm install react-table

React Table is a lightweight and extendable data table for React. It provides a rich set of features like sorting, filtering, and pagination.

Step 3: Define Your Table Columns and Data

In your src folder, open App.js and define your table columns and sample data:

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

function App() {
  const data = React.useMemo(() => [
    { senderID: 'John', receiverID: 'Doe', fileName: 'file1.txt', transactionDate: '2026-01-01', recordCount: 10 },
    // Add more sample data...
  ], []);

  const columns = React.useMemo(() => [
    { Header: 'From', accessor: 'senderID' },
    { Header: 'To', accessor: 'receiverID' },
    { Header: 'Transaction File', accessor: 'fileName' },
    { Header: 'Transaction Date', accessor: 'transactionDate' },
    { Header: 'Record Count', accessor: 'recordCount' },
  ], []);

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

Step 4: Implement the Table with Checkbox Feature

Modify the App.js to render the table and include checkboxes for each row:

return (
  <div>
    <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()}>
              <td><input type="checkbox" /></td>
              {row.cells.map(cell => {
                return <td {...cell.getCellProps()}>{cell.render('Cell')}</td>;
              })}
            </tr>
          );
        })}
      </tbody>
    </table>
  </div>
);

Step 5: Add Custom CSS for Row Height

To adjust the row height, you can apply custom CSS styles. Create a file named Table.css in the src directory:

table {
  width: 100%;
  border-collapse: collapse;
}

th, td {
  border: 1px solid #ddd;
  padding: 8px;
  height: 30px; /* Adjust this value to change the row height */
}

tr:nth-child(even) {
  background-color: #f2f2f2;
}

tr:hover {
  background-color: #ddd;
}

Import this CSS file in your App.js file:

import './Table.css';

Step 6: Testing and Adjustment

Run your application using:

npm start

Open your browser and navigate to http://localhost:3000. You should see your table with the customized row height. Adjust the height property in the CSS file to fit 20 rows on your screen.

Common Errors/Troubleshooting

• Table does not display: Ensure that the useTable hook is correctly imported and used.
• Checkboxes not working: Verify that the input elements are correctly placed within the table rows.
• CSS not applying: Check if the CSS file is imported properly in your component.

Conclusion

By following these steps, you have successfully customized the row height in a React Table. This allows you to tailor the table's appearance to fit specific design needs, such as displaying a fixed number of rows. Customizing table styling in React can greatly enhance the user experience by making your application more intuitive and visually appealing.
