lib/org/parser.js (parseTableRow): Change whitespace.

Hi, Masafumi.  Not being familiar with JavaScript development, I chased down this one for a while :-).

I was unable to ".load org.js" interactively within Node, a bit as if some closing delimiter was missing.
Is it some implied semicolon problem?  Is it a Node bug?  I have no idea.  Yet, reformatting the code
as per this commit seems to repair the difficulty.

Of course, if you understand what the real problem is, or if you have an opinion, please educate me! :-)
