At the beginning, there is no return false, except IE8, the other browser can enter and up and down the key to switch input focus.

But IE8 must add return FALSE. No, it seems that the event is scurrying, debugging into other parts of jquery, I did not chase.

This question is also discussed in HTTP://STACKOVERFLOW.COM/QUESTIONS/1326993/JQUERY-FOCUS-SOMETIMES-NOT-WORKING-IN-IE8. But their methods didn't work. the return to False is solved!

The method of locking the table head recently did not find very good. With floattable, but big table to card a 4, 5 seconds to line, sad.
