How can the code be modified to ensure proper table row and cell formatting?

The code can be modified to ensure proper table row and cell formatting by using the appropriate HTML tags for table rows and cells. Each row should be enclosed within <tr> tags, and each cell within <td> tags. Additionally, CSS styling can be applied to further customize the appearance of the table. 

echo &quot;&lt;table&gt;&quot;;
for ($i = 1; $i &lt;= 3; $i++) {
    echo &quot;&lt;tr&gt;&quot;;
    for ($j = 1; $j &lt;= 3; $j++) {
        echo &quot;&lt;td style=&#039;border: 1px solid black; padding: 5px;&#039;&gt;$i,$j&lt;/td&gt;&quot;;
    }
    echo &quot;&lt;/tr&gt;&quot;;
}
echo &quot;&lt;/table&gt;&quot;;
