Why numbers and why that sequence?

[mkjs]

Hello!
THIS code outputs a table, but the content of the cell sis not empty, there are numbers and still in that way one after another.
My question is simple: why does this code not give empty cells or numbers with no system (random)?

Many thanks, I hope U understood what I had in mind! I actually dont see anything clearly that woudl give such a sequence! MANY THANKS!!!

    <?php
        echo "<table border='1'><br />";

       for ($row = 0; $row < 5; $row ++) {
        echo "<tr>";

       for ($col = 1; $col <= 4; $col ++) {
         echo "<td>", ($col + ($row * 4)), "</td>";
        }

        echo "</tr>";
         }

        echo "</table>";

?>

($col + ($row * 4))

That code is inserting the numbers. If you want different content then replace that with what you do want.
