Great, I had the same situation with setting the innerHTML. When I read this I realised that one of the elements was a TR and one was a TD and the TD was working.

Changing the code so that they're both TDs fixes it, which means that it is a rather non-obvious problem caused by the structure of tables.

Presumably it throws the DOM awry when I start changing table rows since it can't store the table as an array any more.

I'm sure IE could give a more informative error message since it can't be that uncommon for the DOM to change on the fly and it seems strange that this would only throw an error for tables.
