That's not showing up in Chrome for me (I think the formatting of the journal is causing the code to inherit some line height stuff but it's not that weird) but that looks like the width of the table is just a hair too small - try messing with the width of the table in its style tag.
Does it look that way on this page here or only in the journal where you're using it? Helps me know if it's a Safari thing or if it's got something to do with inherited characteristics of the page you're working in.
