Troubleshooting Your Table Sorting Issues: A Comprehensive Guide

Creating a dynamic HTML table using JavaScript is a common challenge, and many developers often encounter issues when trying to display data correctly in rows and columns. If you find that your table isn't sorting as expected, you're not alone! In this post, we will explore a common problem and provide you with a clear, step-by-step solution.

However, there are two key issues that might prevent your table from displaying correctly:

Improper use of innerHTML.

Incorrect HTML structure for the table header.

The Solution

To resolve these issues, follow the structured approach outlined below:

1. Fixing innerHTML Usage

Using innerHTML incorrectly can lead to browsers automatically closing tags, which can disrupt the rendering of your table. Instead of continuously appending to innerHTML, you should build the entire string first using an intermediate variable and then update innerHTML once. Here’s how you can do it:

Another common misunderstanding lies in the proper structuring of the <thead> element in HTML. The header should contain a single row (<tr>) with the column headers specified using the <th> tag. Here’s how to structure it correctly:
