Dynamically Expand Table Rows with Buttons using jQuery

Creating interactive tables can significantly enhance the user experience of a webpage. One common requirement is to allow users to expand or collapse table rows for more information when they click on a button. In this guide, we will walk through how to modify an existing jQuery function to achieve this feature effectively.

The Problem: Expanding Rows with Clicks

You may already have a table set up that expands rows when clicking anywhere in the row. However, you want to allow users to only expand a row by clicking on a button instead. This refinement can provide clearer functionality and accessibility.

The Solution: Implementing Button Clicks for Row Expansion

To solve this, we will update the existing expandTable function so that it targets buttons within the table headers specifically. Here’s how we can achieve this in a few organized steps.

Step 1: Modify the Expand Function

In the original expandTable function, you will need to change the jQuery selector. Instead of capturing clicks on the entire row, modify it to target only the button in the header.

Step 2: Understanding the Selector

The selector $('.header > th > button') specifically targets buttons that are children of <th> elements inside any row with the class header. This ensures that only button clicks trigger the row expansion.

Step 3: Adjust the HTML Structure

Make sure that your table is well-structured. Below is an example of how your HTML table should be set up along with the necessary jQuery and CSS:
