How can PHP developers effectively troubleshoot and debug issues related to displaying data in a table format with multiple columns?

To effectively troubleshoot and debug issues related to displaying data in a table format with multiple columns in PHP, developers can start by checking the data source and ensuring that the data is correctly fetched and processed. Next, they can inspect the HTML table structure to verify that the columns are properly defined and aligned with the data. Finally, developers can use PHP debugging tools like var_dump() or print_r() to examine the data before it is displayed in the table. 

<?php
// Sample data
$data = array(
    array('Name' => 'John Doe', 'Age' => 30, 'Location' => 'New York'),
    array('Name' => 'Jane Smith', 'Age' => 25, 'Location' => 'Los Angeles'),
    array('Name' => 'Mike Johnson', 'Age' => 35, 'Location' => 'Chicago')
);

// Display data in a table
echo '<table border="1">';
echo '<tr><th>Name</th><th>Age</th><th>Location</th></tr>';
foreach ($data as $row) {
    echo '<tr>';
    echo '<td>' . $row['Name'] . '</td>';
    echo '<td>' . $row['Age'] . '</td>';
    echo '<td>' . $row['Location'] . '</td>';
    echo '</tr>';
}
echo '</table>';
?>
