How can PHP developers ensure that all data from a MySQL query is displayed correctly in a table, especially when dealing with multiple tables?

When displaying data from multiple tables in a MySQL query in a table, PHP developers can ensure that all data is displayed correctly by using proper JOIN statements in the query to retrieve related data, and then looping through the results to populate the table rows with the data. 

<?php
// Establish connection to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check connection
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Query to retrieve data from multiple tables using JOIN
$query = "SELECT table1.column1, table2.column2 FROM table1 JOIN table2 ON table1.id = table2.id";

$result = mysqli_query($connection, $query);

// Display data in a table
echo "<table>";
echo "<tr><th>Column 1</th><th>Column 2</th></tr>";

while ($row = mysqli_fetch_assoc($result)) {
    echo "<tr><td>" . $row['column1'] . "</td><td>" . $row['column2'] . "</td></tr>";
}

echo "</table>";

// Close connection
mysqli_close($connection);
?>
