I want write a PHP code to print multiplication table with a certain format. attached is the format i want.

how it works--You have two cells spanned together and the result of those two are are multiplied with the column. this will give you the X like structure in the table.

I have included a code that will only print a multiplication table without that format.
?>
<HTML>
<HEAD>
<TITLE>A division table</TITLE>
</HEAD>
<BODY>
<FORM ACTION="<?php echo $_SERVER[PHP_SELF];?>" METHOD="POST">
<P>Please enter the matrix
<input type ="text"; size=5; name="end_num" VALUE="<?php echo $_POST['end_num']; ?>">
 
<H2>A division table</H2>
<TABLE BORDER=1>
<?php
 print("<TR>\n");
  print("\t<TH> </TH>\n");
  for ($row = $start_num; $row <= $limit; $row++)
  {
  	print("\t<TH>$row</TH>\n");
  }
 
  //print("</TR>\n");
 
  for ($row = $start_num; $row <= $limit; $row++)
  {
    print("\t<TR><TH>$row</TH>\n");
    for ($column = $start_num; $column <= $limit; $column++)
      {
        $result = $row * $column;
        printf("\t<TD>%.3f</TD>\n",$result);  // see Chapter 8
      }
  //  print("</TR>\n");
  }
?>
</TABLE>
</BODY>
</HTML>

May you please clarify what problem you are encountering?  I just inputted two sample variables:

$start_num=4;
$limit=20;

And it generates your multiplication matrix just fine....

Oops sorry I see your file attachment now.....

I don't understand what you are trying to do by doing a colspan on some <TD>'s..... because 2x2 is not the same as 2x3......
