I apologize that I can't double check this, but have you tried using the "disable autoformatting" ticky box? At least on LJ, any carriage returns in the code between table rows get rendered before the table.

So, in your example, I'm referring to the two rows of white space between the /tr and the following tr, which make the code readable when editing it.

Alternatively, you'd need to post the table as one giant wall of text in the editor.
