Simile wiki table editor
Large tables and more advanced table features may be troublesome to edit. This may be easier with the Simile wiki table editor.
Check this page to see how:
If you have more than one table on the same page, you need to have a headline for each table, and have section editing enabled in your preferences. The editor seems to edit only the first table on the page or section you are editing.
The Simile table editor is tested successfully in Firefox.
Note: The wikEd wiki page editor should be disabled while using this table editor.
