1) The columns headers reorder all of the rows of the table according to the contents of their own column. In this case, they reorder everything alphabetically. It's just happens to switch the two rows in the tiny example. I admit it's not super clear why the rows are are changing when all of the example words are so similar to each other... I might try to make things clearer in the future. Hmm!
2) Oops! There should be a button with a butterfly on it to unlock the phone, but it seems like all the phone buttons went missing....
Everything should be all fixed now! Thank you so much for commenting when you ran into a problem, I really appreciate it a lot!
