How to Dynamically Populate an Ant Design Table with API Data in ReactJS

When working with ReactJS, one common challenge developers face is populating an Ant Design Table with data from an API. If you're new to ReactJS, you might find yourself in a situation where you can only fill tables with constant variables, while struggling to utilize data fetched from an API. In this guide, we’ll walk through how to correctly implement a responsive table that retrieves and displays data dynamically.

The Problem

You may want to fill an Ant Design Table with data obtained from an API. However, while attempting to set up your useEffect for fetching the data and populating your table, you might encounter a few hurdles:

You can populate a table using constant variables, but not with data fetched in the useEffect.

There’s a risk of creating recursive calls in your useEffect, leading to unintended behavior.

Understanding the Structure

Before diving into the solution, let’s analyze your current setup. Here’s a simplified breakdown of the important components:

State Management: You are managing your API data with useState.

Fetching Data: You're using useEffect to fetch data from the API.

Setting Up Table Schema:

Columns are defined in a schema (project) for the Ant Design Table.

Uses a constant variable candidature for initial fake data.

Solution Overview

Here's how to correctly set up your React component to dynamically populate the Ant Design Table with your fetched data:

Step 1: Define Your Columns with Render Functions

Instead of embedding HTML directly into your data source, make use of the render function in your table schema. This method allows you to customize how data is displayed in each cell.

Step 2: Fetching Data with useEffect

In your useEffect, make sure to remove candidatures from the dependency array to prevent recursion. Only include items that are not changing with each render.

Step 3: Rendering the Table

With your columns defined and your data fetched, render the table using the state you populated with the API data.

Conclusion

By following these steps, you can successfully populate an Ant Design Table with data fetched from an API without facing recursion issues. Remember to keep your data passed to the Table schema simple, and use the render function for any necessary HTML formatting.

With these techniques, you’ll be able to create crisp and efficient data-driven components in your React applications. Happy coding!
