"No parameters can be added to |- tags; not that I ever saw a table on wikipedia which uses that!"

If you search the en: cur sql dump file for '<tr ' you will find hundreds of examples;

Most are in these categories: <tr style=background:#efefef ;> <tr valign="bottom"> <tr bgcolor="#CCFFFF"> <tr align="center">

Secondly, I suggest using another character for captions.

|_ is too similar to |- and therefore hard to detect when editing the source, easy to confuse and mistype.
