What are some best practices for overlaying images on tables in PHP?

When overlaying images on tables in PHP, it is important to ensure that the images are properly aligned and displayed on top of the table cells. One way to achieve this is by using absolute positioning for the images and setting the z-index property to ensure they appear above the table. Additionally, it is important to make sure the images are the appropriate size and have transparent backgrounds to seamlessly overlay on the table.

<!DOCTYPE html>
<html>
<head>
    <style>
        table {
            position: relative;
        }
        img {
            position: absolute;
            top: 0;
            left: 0;
            z-index: 1;
        }
    </style>
</head>
<body>

<table border="1">
    <tr>
        <td>Cell 1</td>
        <td>Cell 2</td>
    </tr>
    <tr>
        <td>Cell 3</td>
        <td>Cell 4</td>
    </tr>
</table>

<img src="image.png" alt="Overlay Image" width="50" height="50">
