Skin for tables

When I insert a table I get the feeling I'm edition a webpage from the early 90's, default tables i HTML are ugly. There should be a way to choose a skin for the table, with the ability to choose the top row or the left column as header. I often manually edit the HTML and CSS to get the tables looking decent.

And a default skin should be a simple flat table with black 1px solid borders around all cells, and the headers with a light grey background or something. You get the idea ;)

It should be a part of the existing wiki styles, so that different styles (can) have different default look for the tables.
