在windows中，可以用哪个Win32::OLE来操作excel，如：

#!/usr/bin/perl -w 
use Win32::OLE;
$class = 'Excel.Application'; 
$app = Win32::OLE->new( $class ) or die "Cannot connect to Excel, $!"; 
$app->{'Visible'} = 1; 
$app->Workbooks->Add(); 
# Set values in a "range". 
$app->Range("A1")->{'Value'} = "A"; 
$app->Range("B1")->{'Value'} = "B"; 
$app->Range("B2")->{'Value'} = "C"; 
$app->Range("C2")->{'Value'} = "D"; 
$app->Range("B3")->{'Value'} = 10; 
$app->Range("C3")->{'Value'} = 10; 
# Leave Excel running. Use $app->Quit() to exit. 
$app->Quit();
