Advice for posting stats?

I'm having a miserable time posting stat tables on this site, so I thought I'd solicit those reading this for help. Here's the rundown of what I've tried:

• Until recently, copying-and-pasting from Excel into blogger has worked great. Now, however, I'm finding that only the lines for the rows are showing up. Column lines are not, which makes many of my (cramped) tables hard as heck to read. This seems to be a browser issue, as it happened once I upgraded to the latest FireFox. But I need this site to be readable by any browser, so that's no help. I've tried every manipulation of the table html code I can think of, and nothing seems to be working.
• I've also tried using the "pre" & "/pre" html tags to just post preformatted text (see below). Unfortunately, blogger seems to remove any spaces I leave in this text when I post a message. So that's no good either.
• I've also tried taking a screen capture of the table in excel and then posting that graphic to this site. Unfortunately, blogger resizes any images I post here once they get wider than half a screen length. Most of my tables are fairly wide, which makes them all-but-unreadable.
  
• I've also borrowed a page from Joel Luckhaupt at RedsAndBlues.com (as an aside, congrats to Doc Scott and JP on their new site) and used EditGrid. This looks terrific (see here), but unfortunately I am unable to edit these posts once I publish them due to some sort of bug with the blogger software. And none of the other online spreadsheet programs seem to have the ability to imbed a small table into a website like editgrid does.
  

So, anyone else have any ideas? Thanks if you do. I'm sending this request to blogger as well, so if they get back to me with anything I'll post their solution here.
