The textbook gives no explanation. I included a pdf with just a few examples. Thanks! Twyla Attachments:You must be logged in to view attached files.

Perhaps the publisher’s website includes an “About the Book” section or other commentary that might shed light on this design. If the lines aren’t mentioned, and you don’t find a pattern of which tables have which lines, I would be tempted to ignore them. –Kyle Author Posts Viewing 2 posts - 1 through 2 (of 2 total) Everyone is free to read the forums, but only current NBA members can post.
