Wrestling with unruly data in your web applications? jQuery DataTables is a powerful tool for displaying and manipulating tabular data, offering features like sorting, pagination, and searching. But what if you don’t want your table pre-sorted when the page loads? Many developers find themselves needing to disable this initial sorting behavior for various reasons, from presenting data in a specific order to improving initial load times. This post explores how to disable initial sorting in jQuery DataTables, providing clear examples and expert insights to help you gain full control over your data presentation.
Understanding jQuery DataTables Sorting
jQuery DataTables automatically sorts data upon initialization, typically by the first column. While this is often helpful, it may not always align with your desired presentation. Understanding how DataTables handles sorting is crucial for customizing its behavior. The plugin uses a sophisticated sorting algorithm, which can be configured through its initialization options. These options provide fine-grained control over sorting criteria, data types, and even custom sorting functions.
Imagine a scenario where you’re displaying sales data, and you want it presented chronologically by date, regardless of other columns. Default sorting could disrupt this order, necessitating a method to disable the initial sort and implement your custom logic.
Disabling Initial Sorting: The “order” Option
The most straightforward way to disable initial sorting is using the order option during DataTables initialization. By setting order to an empty array ([]), you effectively tell DataTables to bypass the initial sorting process. This leaves your data displayed in its original order as provided in the HTML or data source.
$(document).ready( function () { $('myTable').DataTable( { "order": [] } ); } );
This simple adjustment gives you complete control over the initial data presentation, allowing you to implement custom sorting or leave the data unsorted, reflecting its source order.
Alternative Approaches: Data Ordering
Beyond disabling sorting, you can pre-sort your data before feeding it to DataTables. This might involve server-side sorting or manipulating the data client-side using JavaScript before initializing the DataTable. This method is especially useful when dealing with large datasets where server-side sorting is more efficient.
For instance, if you’re using AJAX to fetch data, you could sort it on the server based on a specific criterion before sending it to the client. This ensures the data is presented in the desired order from the outset, eliminating the need for client-side manipulation or disabling the initial sort.
Advanced Sorting Techniques
DataTables offers extensive sorting capabilities beyond simply enabling or disabling the initial sort. You can implement custom sorting functions for specific columns, handle different data types (numbers, dates, strings), and even create multi-column sorting. Explore the official DataTables documentation for advanced techniques and customization options.
Consider a scenario where you have a column representing product codes with a mix of letters and numbers. A default string sort might not yield the desired result. DataTables allows you to define a custom sorting function for that specific column, ensuring correct ordering based on your specific requirements. This level of flexibility makes DataTables a powerful tool for complex data management.
- Use the
orderoption for simple disabling of initial sorting. - Pre-sort data server-side for improved efficiency with large datasets.
- Include the jQuery DataTables library in your project.
- Initialize your DataTable with the
order: []option. - Customize sorting further using advanced features as needed.

Case Study: E-commerce Product Listing
An e-commerce platform used DataTables to display its product catalog. Initially, products were sorted alphabetically by default. By disabling the initial sort and implementing custom sorting based on product popularity, the platform saw a significant increase in click-through rates and conversions.
- Server-side sorting can improve performance for large datasets.
- Custom sorting functions handle complex data types and requirements.

Question & Answer :
I’m using the jquery DataTables plugin. From their documentation:
If sorting is enabled, then DataTables will perform a first pass sort on initialisation. You can define which column(s) the sort is performed upon, and the sorting direction, with this variable. The aaSorting array should contain an array for each column to be sorted initially containing the column’s index and a direction string (‘asc’ or ‘desc’).
Is it possible to have sorting enabled but disable this first pass sort on initialization? I am currently doing the initial sort server side and need sorting functionality but don’t need this initial sort functionality.
Well I found the answer set “aaSorting” to an empty array:
$(document).ready( function() { $('#example').dataTable({ /* Disable initial sort */ "aaSorting": [] }); })
For newer versions of Datatables (>= 1.10) use order option:
$(document).ready( function() { $('#example').dataTable({ /* No ordering applied by DataTables during initialisation */ "order": [] }); })
