What debugging techniques can be employed to identify and resolve issues with outputting values in certain columns of an HTML table using PHP?

The issue with outputting values in certain columns of an HTML table using PHP could be due to incorrect indexing or data manipulation errors. To resolve this, you can debug the code by checking the array or database query results, ensuring that the correct values are being fetched and displayed in the respective columns of the table. 

// Assuming $data is an array of values to be displayed in the table
echo "<table>";
foreach ($data as $row) {
    echo "<tr>";
    echo "<td>" . $row['column1'] . "</td>"; // Display value in column 1
    echo "<td>" . $row['column2'] . "</td>"; // Display value in column 2
    // Add more columns as needed
    echo "</tr>";
}
echo "</table>";
