Expert Help needed! .Display spreadsheet in a browser

[sharugan]

I have a spredsheet that contains the data.I need to display the spreadsheet in a browser when the user types the url of the website.It should n't pop up "save as" dialog box to open / save the spreadsheet.
I am using the following code , but it opens the pop up window.How do i avoid the pop up window.
I also tried <a herf="one.xls"> in html . that also opens the pop up windows.
<?php

$export_file = "worldmap.xls";
ob_end_clean();
ini_set('zlib.output_compression','Off');

header('Pragma: public');
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT');
header('Cache-Control: no-store, no-cache, must-revalidate'); // HTTP/1.1
header('Cache-Control: pre-check=0, post-check=0, max-age=0'); // HTTP/1.1
header ("Pragma: no-cache");
header("Expires: 0");
header('Content-Transfer-Encoding: none');
header('Content-Type: application/vnd.ms-excel;'); // This should work for IE & Opera
header("Content-type: application/x-msexcel"); // This should work for the rest
header('Content-Disposition: attachment; filename="'.basename($export_file).'"');


?>

unless you render the content of the spreadsheet as html, you cannot control the behaviour of the browser (i.e. to dire up an excel reader plugin) from php.
