To create dynamic column headers in a datatable from a JSON array, you can use the popular DataTables jQuery plugin along with some JavaScript code to populate the column headers dynamically. Here's a step-by-step guide:
- Include Required Libraries: Make sure to include the necessary libraries in your HTML file. You'll need jQuery, the DataTables library, and the Bootstrap CSS for styling (optional).

<title>Dynamic Column Header in DataTable</title>

<script src="https://cdn.datatables.net/1.11.5/js/jquery.dataTables.min.js"></script>
</head>
<body>
<table id="dynamicTable" class="display" style="width:100%"></table>
<script>
// Your JavaScript code goes here
</script>
</body>
</html>
- Prepare JSON Data: Assume you have a JSON array containing your data, where each object represents a row in the table. Each object should have properties corresponding to the column headers.
javascriptconst jsonData = [
{ id: 1, name: 'John', age: 30, country: 'USA' },
{ id: 2, name: 'Alice', age: 25, country: 'Canada' },
// Add more rows as needed
];
- Create the DataTable: Now, create the DataTable and dynamically generate the column headers based on the properties in the JSON data.
javascript$(document).ready(function() {
// Get the keys from the first row of the JSON data
const columnHeaders = Object.keys(jsonData[0]);
// Create the table
$('#dynamicTable').DataTable({
data: jsonData,
columns: columnHeaders.map((header) => ({ title: header, data: header })),
});
});
In this code, we use the Object.keys() function to get the column headers from the first row of the JSON data. Then, we use the columns option of DataTables to dynamically create the table headers based on these keys.
By following these steps, your DataTable will have dynamic column headers populated from the JSON array, allowing you to display and interact with your data in a structured and customizable manner.
