This is a follow up to bug 109184. The remaining issue is that when DOCX tables with no fill background are roundtripped in Writer, the following element is added to the file: <w:shd w:fill="auto" w:val="clear" /> This is unnecessary, as it's the default, and Word doesn't insert the element with such attributes. Open&save attachment 135592 [details] (created in Word) in Writer. Check document.xml in the resulting file.
