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......
