[xwiki-users] Table Alignement

Hi ! I've been struggling for hours trying to get a Html table centered on a wiki page. I tried all the suggested syntax I found in the very messy Xwiki documentation (i.e, using style="etc.", then using class="myclass") and I also tried to get rid of all table references in the colibri.css file, but STILL, my table is stuck on the left. It's just driving me nuts to be able to hit a database in a record time and to spend hours to get the resulting table centered! Any clue? Why is all the rendering locked this way? What's the point ? By the way, I am running XWiki Enterprise 2.5.1.32531 Thanks Marc
