Erin – this may be too late or there may be a more elegant solution to this now, but here’s how I’ve managed it. Select and copy your table in Excel. Then go to Live Writer (I’m using 1.0 in Beta) and select “Paste Special”, choose the “Keep Formatting” option. The table will paste just as it looks in Excel. It comes with a little too much html code but you can edit out rows etc. And it’s quick! I imagine other desktop blogposting clients can do similar things – I think Blogjet promised something similar. But this works.
