If a line break is made here, > *make htmldocs* warns 'Malformed table'. Thanks for the info. Compare to the warning and a space in webpage, I'd prefer using line break for a neat source doc.

I've already checked the HTML page, > the rendering effect is OK. Uh, that's a bit inconvenitent for us. we'd better to double check the '=' to make sure it fit the chars number correctly. Thanks Alex
