Trouble Adding 2D Array Contents on an HTML Table

Creating a game like Battleship can be an exciting project, especially when working with HTML and JavaScript to visualize the game board. However, sometimes you might run into issues when trying to display elements from a 2D array onto an HTML table correctly. If you're encountering problems with your Battleship game and the table isn't showing the ship positions as intended, you’re not alone. Let's break it down and fix it together!

Understanding the Problem

Your goal is to take a 2D array (let’s call it p1Board) that contains the positions of the ships and display it in an HTML table. The function responsible for this task is displayTable, and while it is correctly set for the intended actions, there is a small but critical mistake that prevents it from functioning properly:

The loop iterating over the columns in the table is not structured correctly, specifically regarding how it accesses the cells of each row.

The Original Code

Here's the function you shared, which is meant to render the game board:

When you run this code, the table displays correctly, but the ship positions do not appear as intended. Let's address the reason behind this issue.

Proposed Solution

Identifying the Problem

The problem lies in the way you are accessing the cells in your loop. Specifically, the line:

The Fix

To correct the issue, you need to reference the specific row of the table while accessing the total number of cells. Therefore, the revised line should look like this:

Conclusion

By making this simple adjustment, your table should now correctly display the ship positions pulled from the p1Board 2D array. This fix enhances your implementation of the Battleship game, bringing you one step closer to finalizing your project. Remember, debugging often involves such minor yet significant errors in code, so always ensure proper access to data structures.

With this revised function, you can continue developing your game confidently. Happy coding!
