Getting Started with Installation

To begin using @handsontable/react, install it via npm or yarn:

npm install handsontable @handsontable/react

Or, if you prefer yarn:

yarn add handsontable @handsontable/react

Basic Usage in Your React Application

Setting Up Your First Grid

Start by importing the necessary components and styles:

import { HotTable } from '@handsontable/react';
import 'handsontable/dist/handsontable.full.min.css';

const App = () => {
  const data = [
    ['', 'Tesla', 'Volvo', 'Toyota', 'Ford'],
    ['2019', 10, 11, 12, 13],
    ['2020', 20, 11, 14, 13],
    ['2021', 30, 15, 12, 13]
  ];

  return (
    <div id="hot-app">
      <HotTable
        data={data}
        colHeaders={true}
        rowHeaders={true}
        width="600"
        height="300"
      />
    </div>
  );
};

This basic setup initializes a simple data grid within your React application.

Customizing Your Grid

You can customize your grid further by adjusting its properties. For example:

<HotTable
  data={data}
  colHeaders={['Year', 'Tesla', 'Volvo', 'Toyota', 'Ford']}
  rowHeaders={['Row1', 'Row2', 'Row3']}
  width="800"
  height="400"
/>

Advanced Techniques for Power Users

Implementing Data Validation

To ensure your data maintains its integrity, you can implement validation rules:

const validateData = (value) => {
  return value !== '' && !isNaN(value);
};

<HotTable
  data={data}
  colHeaders={true}
  rowHeaders={true}
  cells={(row, col) => {
    const cellProperties = {};
    if (col > 0) {
      cellProperties.validator = validateData;
    }
    return cellProperties;
  }}
/>

Utilizing Conditional Formatting

Enhance your grid’s readability by applying conditional formatting:

<HotTable
  data={data}
  colHeaders={true}
  rowHeaders={true}
  cells={(row, col) => {
    const cellProperties = {};
    if (col > 0 && row > 0) {
      cellProperties.className = data[row][col] > 15 ? 'highlight' : '';
    }
    return cellProperties;
  }}
/>

Wrapping Up

The @handsontable/react library is a powerful addition to any React developer’s toolkit. With its rich set of features and ease of integration, it allows you to create interactive and intuitive data grids that enhance user experience. Whether you’re handling complex datasets or just need a simple table, this library provides the flexibility and functionality you need to succeed in your projects.
