I'd like to set a default of valign=middle for all new tables in every document.

Is that possible?

Try putting this into the head section of your document:

<style type="text/css">

tr {vertical-align:middle}

</style>

You could save it as a template so that you can use it again and again.

Not sure if it did anything. I keep getting weird results between what I see in "WYSIWYG" and what comes out when the page is actuallly uploaded.

And looking at the code, it still has valign center instead of middle in the actual table stuff.

Did I do it wrong?

Oh, and now when I preview the page in MS Internet Explorer, I see little squares on the left side of the page.
