How to Access Nested Fields in React-Bootstrap-table ?

React-Bootstrap-Table provides a set of components and utilities that make it easy to create tables with features like sorting, filtering, pagination, and more. To access nested fields in React-Bootstrap-Table, you can use the dataField property of your column definitions to specify the path to the nested field in your data.

• Step 1: Create a React Application using the below command

npx create-react-app <foldername>

• Step 2: After creating your project folder i.e. <foldername>, move to it using the below command.

cd foldername

• Step 3: After creating the ReactJS application, Install the required modules using the below command.

npm i react-bootstrap-table-next

import BootstrapTable from 'react-bootstrap-table-next';
import 'react-bootstrap-table-next/dist/react-bootstrap-table2.min.css';

Example: Now write down the following code in the App.js file. Here, in the App.js file we will import and render the <MyTable/> Component. Lets see the code for MyTable.jsx file.

Javascript

import React from 'react';
import BootstrapTable from 'react-bootstrap-table-next';
import
'react-bootstrap-table-next/dist/react-bootstrap-table2.min.css';

const columns = [
  {
    dataField: 'id', // Top-level field
    text: 'ID',
  },
  {
    // Access the nested 'name' field of
    // the 'geek' object
    dataField: 'geek.name',
    text: 'Name',
  },
  {
    // Access the nested 'age' field of the 'geek' object
    dataField: 'geek.age',
    text: 'Age',
  },
];


const MyTable = ({ data }) => {
  return <BootstrapTable keyField="id"
                           data={data}
                         columns={columns} />;
};

export default MyTable;

• Now, lets import the MyTable.jsx component in the App.js file.

Javascript

import './App.css';
import MyTable from './MyTable';

function App() {
    const data = [
        {
            id: 1,
            geek: {
                name: 'Mahesh',
                age: 30,
            },
        },
        {
            id: 2,
            geek: {
                name: 'Ramesh',
                age: 25,
            },
        },
        {
            id: 3,
            geek: {
                name: 'Suresh',
                age: 20,
            },
        },
    ];
    return (
        <div className="App">
            <MyTable data={data} />
        </div>
    );
}

export default App;

Step to Run Application:

• Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
