Microsoft states that to use the option “Edit in Datasheet” you need at least Office 2003 or 2007 professional edition. I just came across a blogpost which presents use with a cheat;
Open your registry and change this key:
[HKLM\Software\Microsoft\Office\11.0\Common\ProductVersion]
“ProInfo”=dword:00000001
Now you can use this option with Office Standard or Small Business Edition. You don’t even have to restart Internet Explorer.
Haven’t tested it myself by the way………..
