Dynamically Prepend Header Text to Table Cells Using jQuery

If you're working with tables generated by a backend system, you may encounter a situation where the number of columns in the table varies. This can make it challenging to apply the same jQuery functions across all tables. In this guide, we will explore how to efficiently prepend header text to each corresponding body cell using jQuery, regardless of the number of columns.

The Problem: Variable Column Count

When dealing with dynamic tables, it’s common to run into issues like:

The table can have multiple columns (e.g., 3, 4, or more).

You want to add header text as a prefix to the cells of each row.

Writing a static jQuery code for each potential case is impractical and inefficient.

Example Table Structure

Consider a simple table that might look like this:

Here, we want to prepend each header text (like “Month” and “Savings”) to the corresponding cells in the body rows.

The Solution: Using a Loop

To solve this problem, we can use jQuery's .each() function with a loop that iterates over each header element. This way, we can dynamically get the text from each header cell and prepend it to the corresponding body cells.

Step-by-Step Code Implementation

Let’s break down the implementation into clear steps.

Set up jQuery: Ensure you include the jQuery library in your HTML.

Conclusion

By using a loop with jQuery, you can easily manage dynamic tables without worrying about hardcoding specific scenarios for different column counts. Now, regardless of how many columns your table may have, the header text will always be prepended to each corresponding cell, improving the readability of your data.
