How do you get Word 2010 to spell check inside tables?
"Under the 'Review' tab at the top of the screen click on 'Set Language'. When the window appears click 'Default' and the 'Ok'. This will reset the options and allow word to proof again"
This one worked for me!
Cheers
Try selecting your entire table, then click the Language button in the statusbar and make sure that "Do not check spelling and grammar" is not checked.
