[SOLVED] need to create a blank cell block?

[djcrisp22]

i am new here in this forum.  i have this problem creating a cell that needs to be empty? here is my code.  this will create a table.  on the very first block, how can i get it to be empty.  and also add color? for example, the whole first vertical and horizontal row to be colored and numbered from 1 to 12.  and the first block needs to be empty?  any help is appreciated. if u can give me any hints.  php is very difficult to learn. thanks in advance

 

<?php 

echo "<table style=\"border: 1px solid black;\"> \n";

for ($y=1; $y<=12; $y++) {

    echo "<tr> \n";

     for ($x=1; $x<=12; $x++) {

           echo "<td style=\"border: 1px solid #000; width: 25px; padding: 4px;

                       text-align:center;\">";

              echo ($x * $y);

              echo "</td> \n";

        }

          echo "</tr> \n";

             }

       echo "</table>";

        ?>
