How to Properly Sort and Render a Table in ReactJS

Rendering data in a table format is a common task in web development. When building applications with ReactJS, one might encounter the challenge of sorting table data effectively and maintaining the user interface's responsiveness. In this post, we will address a common query: How to sort and render a table in ReactJS properly? We will provide a comprehensive guide for implementing this functionality effectively.

The Problem

Imagine you have a dataset represented as a table, and you want the ability to sort this data either by ascending or descending order based on a column. Perhaps you have already implemented this functionality in pure JavaScript, but the transition to React can be confusing. This often leads to questions like:

How do I recreate the body of the table every time I change the data?

How can I handle sorting without unnecessarily re-rendering the component?

Is there a better way to manage the sorting logic?

These are all valid points, and they reflect a common learning curve when moving to React.

The Solution

Let's break down the solution into clear, organized sections to effectively sort and render the table in ReactJS.

1. Store Data in State

In React, the best practice for handling dynamic data like a table is to store the current data in the component's state using the useState hook.

2. Create a Sorting Function

The sorting function will be responsible for sorting the data either in ascending or descending order based on a specific column – in our case, the price.

3. Simplify the Sorting Logic

You can simplify your sorting logic by implementing a one-directional sort method. For example, if sorting only in ascending order, you don’t need a clickOnPrice variable to toggle direction, hence it can be removed. Adjust your function like so:

4. Update the Table Header

Ensure the button in your table header correctly calls your sorting function. Instead of using an inline arrow function, you can directly pass the function reference to the onClick handler.

5. Render the Table Rows

Finally, use the map() function to render each row of the table dynamically based on the data in your state.

Conclusion

Sorting tables in ReactJS does not need to be complicated. With the effective use of state and structured component logic, you can easily implement this feature without creating unnecessary complexity. By following this step-by-step guide, you should now have a better understanding of how to handle data sorting and rendering in your React applications.
