Thread:Project:Support desk/Beginner's question: formatting tables

I don't have much experience with MediaWiki yet - so far I've been reading through the help pages and trying things out. What I can't seem to figure out is how to create nice looking tables.

The MediaWiki help only shows how to create tables with very wide borders and I don't like this layout very much. Even if I set "border" to "1" the tables look much to bulky. How can I create tables with thinner lines, such as the ones used in Wikipedia?
