How can colspan be effectively used in PHP to address incomplete table filling?

When dealing with incomplete table filling in PHP, the colspan attribute can be effectively used to span multiple columns and ensure a consistent table structure. By using colspan, you can merge cells in a row to accommodate missing data and maintain the overall layout of the table.

echo "<table border='1'>";
echo "<tr>";
echo "<td>Row 1, Column 1</td>";
echo "<td>Row 1, Column 2</td>";
echo "</tr>";
echo "<tr>";
echo "<td colspan='2'>Row 2, Spanning Two Columns</td>";
echo "</tr>";
echo "<tr>";
echo "<td>Row 3, Column 1</td>";
echo "<td>Row 3, Column 2</td>";
echo "</tr>";
echo "</table>";
