Introduction

HandsonTable Community Edition is an open source JavaScript Spreadsheet used in producing spreadsheet component for web applications. HandsonTable is a JavaScript and HTML 5 User Interface (UI) component that you can integrate in your applications. It supports Vue, React, Angula and Polymer.

For this tutorial, we are going to design a simple web page and integrate the HandsonTable spreadsheet using HTML5 and JavaScript. There are many ways where HandsonTable can be such as editing a database, analyzing sales or financial reports, data management etc.

There are various features that HandsonTable provide such as sorting of data, validating data, conditional formatting, freezing, resizing and moving rows/columns, adding comments to cells etc. for this tutorial, we are going to make use of data sorting, resizing rows/columns, adding columns and dragging cells to populate data.

STEPS

Setting up Web page
Follow the steps below carefully to achieve the desired goal;

Launch your text editor and create a file named “index.html”.
Declare the standard HTML5 elements used in defining a document;

 <!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <meta name="description" content="">
    <meta name="author" content="">
    <title>Utopian-io – HandsonTable Spreadsheet Web Component</title>
  </head>
<body>
    
</body>
</html>

We will use bootstrap’s HTML/CSS framework to set up the web page. I downloaded and included it locally. Visit the website https://getbootstrap.com/ to also download or use their CDN links.
We add the following piece of code from the picture below within the body tag to setup the navigational menu and main body of the web page.

Integrating HandsonTable Spreadsheet

We are now going to integrate the HandsonTable Spreadsheet into our web page. First, head over to the HandsonTable Community Edition website https://handsontable.com/community-download to download it. We have the option of downloading the Zip Archive, installation through npm or including the CDN links directly into our web page.

For this tutorial, we are going to use the CDN links. The CSS and JS links are;

CSS:

<link href="https://cdnjs.cloudflare.com/ajax/libs/handsontable/0.35.1/handsontable.min.css" rel="stylesheet">

JS:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/handsontable/0.35.1/handsontable.min.js"></script>

Copy the CSS CDN link and paste within the <head> tag after bootstrap and the JS after the bootstrap JS file at the bottom of the page.

Adding the Spreadsheet component

To add the spreadsheet, we need to create a <div> tag within the main body of the page.

<div id="employee">
</div>

Add the following JavaScript code to initialize the spreadsheet;

<script type="text/javascript">
var data = [{
  "first_name": "Martita",
  "last_name": "Nutkins",
  "email": "[email protected]",
  "gender": "Female",
  "ip_address": "80.215.109.49"
}, {
  "first_name": "Coletta",
  "last_name": "Carnall",
  "email": "[email protected]",
  "gender": "Female",
  "ip_address": "81.195.227.229"
} ]
</script>

The piece of code above is JSON Data. The var data stores the list of employees. The JSON data was generated using https://www.mockaroo.com/. A tool used in generating mockup data.

var container = document.getElementById(employee);
        var hot = new Handsontable(container, {
          data: data,
          rowHeaders: true,
          colHeaders: false,
          colHeaders: ['Firts name', 'Last name', 'email', 'Gender', 'IP Address'],
          columnSorting: true,
          sortIndicator: true
        });

Add the following piece of code above after var data is enclosed to initialize and configure the spreadsheet;
Meaning of the HandsonTable options we used;
- data: data, = reference the variable data we store the JSON objects
- rowHeaders: true, = to display a counter for the rows populated
- colHeaders: false, = this disables the default spreadsheet column header of ‘A-Z’
- columnSorting: true, = this enables data sorting
- sortIndicator = true = this displays an arrow on a sorted column
For more options check the handsonTable Spreadsheet documentation

Preview
It’s working…

As you can see the arrows highlighting the key areas we worked on. The top arrow shows the email was sorted and displaying the sortIndicator. The second arrow shows that two rows were drag and data is being inputted into a cell.
