May you copy then paste the table in a new document ?
With a bit of luck it will behave correctly.
If it doesn't, change the private values then send the modified document to my maibox (click my blue name to get my address).
Of course, you may also try to open the document from an alternate user account.

I was having the same problem. That's how I ended up here. But then it occured to me that I had filtered the table on a certain value. I reset the filter and all is well. It makes sense: you can't add to afiltered view because the new row wouldn't have the filtered value yet. And if it allowed a blank row you might enter a value contrary to the filter.
