I just did a quick search, so I don't claim to be an expert. The two main methods seem to be thead/tfoot and position:fixed. I didn't mean to imply that this are smarter/better, but they might be easier in certain conditions.
Oh, I see, thanks. I did figure out that thead automatically repeats across pages, but I also had to repeat other stuff outside the table, like letterhead.
I also made this sample file that shows thead repeating, but since it's a single continuous table it doesn't preview very well and spills out of the 8.5x11 article element. I'm not sure how I would take advantage of the browser's automatic thead/tfoot repeat while also accurately previewing the result in the browser, especially with more elements below the table.
