How to get cell value on React-Table ?

React-Table is a powerful library that allows you to create flexible and feature-rich tables in your React applications. It provides various functionalities to manipulate and interact with table data. One common requirement is to retrieve the value of a specific cell in React-Table. In this article, we will explore React Table.

Some Features of React Table:

• Lightweight (5kb-14kb+ depending on features used and tree-shaking).
• Headless (100% customizable, Bring-your-own-UI).
• Auto out of the box, fully controllable API.
• Sorting (Multi and Stable)
• Filters.
• Pivoting & Aggregation.
• Virtualizable.
• Resizable

Get Cell Value: We can get the cell/column value of the table by adding the onClick event to the <td> tags.

getCellValue function : onClick={()=> setCellValue(cell.value)}

Creating React Application And Installing Module:

Step 1: Create a React application using the following command.

npx create-react-app foldername

Step 2: After creating your project folder i.e. foldername, move to it using the following command.

cd foldername

Step 3: After creating the ReactJS application, Install the react-table using the following command.

npm i react-table

Project Structure: It will look like the following:

Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

Javascript

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

const App = () => {

    // Define state
    const [cellValue, setCellValue] = useState('');

    // Add data here to show in table
    const data = React.useMemo(
        () => [
            {
                reactCol1: 'Hey',
                reactCol2: 'World',
            },
            {
                reactCol1: 'Here',
                reactCol2: 'is the',
            },
            {
                reactCol1: 'Example',
                reactCol2: 'of react-table',
            },
        ],
        []
    )

    // Define column of the table
    const columns = React.useMemo(
        () => [
            {
                Header: 'React',

                // Accessor is the "key" in the data
                accessor: 'reactCol1',
            },
            {
                Header: 'Table',
                accessor: 'reactCol2',
            },
        ],
        []
    )

    // Function to get cell value
    const getCellValue = (cell) => {
        setCellValue(cell.value)
    }

    // Create the instance of table by
    // using hooks of react-table
    const {
        getTableProps,
        getTableBodyProps,
        headerGroups,
        rows,
        prepareRow,
    } = useTable({ columns, data })
