Fixing React Table Sorting: Why It Requires Two Clicks and How to Solve It

If you're working with React and encounter a frustrating issue where your sortable table only sorts data after two clicks instead of just one, you're not alone. This issue arises from the way state updates are managed in React, particularly when using hooks like useEffect. In this post, we will delve into the underlying problem and provide an effective solution to ensure your table sorts with just a single click.

Understanding the Problem

When you click to sort a column in your table, the useEffect hook is responsible for detecting changes in the sorting order and updating the displayed data. However, there's a timing issue with React's rendering lifecycle.

Why Does it Require Two Clicks?

React Rendering Sequence: Upon clicking the column header, React first renders the component with the latest state (the unsorted data), and then the useEffect hook runs to sort the data.

Order of Operations: Because the sorting logic executes after the render, you need to click again for the sorted data to display.

Current Code Implementation

In your current implementation, you are using a custom hook (useFetch) that relies on useEffect to sort data after the initial render. Here's a snippet of the relevant code:

The Solution: Simplified State Management

To eliminate the delay caused by needing two clicks, we can refactor the useFetch hook to manage state differently by directly updating the data whenever the order is set.

Revised Hook Implementation

The new implementation involves a custom setter function to handle both the order and the data updates simultaneously. Here’s how you can do that:

Updated Component Integration

Now you can integrate this updated hook into your component effectively, ensuring a smoother user experience. Here's how the component AcceptedOffers would look:

Conclusion

By reworking the way we update state within our sortable table, we can effectively reduce the number of clicks needed from two to one for sorting. This approach improves the user experience and ensures that the sorting dynamics function as intended.
