What role does the browser play in determining whether table backgrounds are printed when using PHP?

The browser determines whether table backgrounds are printed by its default settings for printing background colors and images. To ensure table backgrounds are printed, you can use CSS to explicitly set the background properties for the table and its cells.

<style>
  table {
    background-color: #ffffff; /* set background color for table */
  }
  td {
    background-color: #ffffff; /* set background color for table cells */
  }
</style>

<table>
  <tr>
    <td>Cell 1</td>
    <td>Cell 2</td>
  </tr>
</table>
