If you're going to have a big table, you're going to want to avoid putting in any carriage returns. That blank space below the table is each return in the table code showing up once the table ends. With long tables (like I did with the TV Ratings back in the day), it's a ridiculously long empty space.
I think you're supposed to get an error but it may flash by so quickly you end up back at the index page before you know what's happened. (Usually, you can hit "back" and figure out you didn't put a title in the title box, though.
