If you're assembling a lengthy table in Word, then having to copy the table headers onto each page can be a nuisance. Fortunately, you don't have to thanks to a somewhat-buried option.
Microsoft's Word blog presents the shortcut via an extremely cheesy video (you can see it below), but in essence it's very simple. Once you've created a table in Word 2007 or 2010, two new ribbon tabs, Design and Layout, appear under the awkwardly-placed Table Tools heading.
On the Layout tab, click on Repeat Header Rows and the header row will have its contents repeated on subsequent pages. (It would be helpful for Microsoft to also flag this ability on the Insert table dialog, but at least the option is there.)
