I am transferring content from a mediawiki to a Tiki-wiki. My Tiki-wiki is open for editing by guests, so I do not want to enable the html tag as it supports js and thus is unsafe. Simple tiki-syntax tables do not even support rowspan. FANCYTABLES seems to be a translation for html tables, but it is not documented how to use colspan. Nesting tables seems also not supported in both of them.
Is there any safe way to create a table using colspan and rowspan? I did not anticipate tiki to have only such basic support for tables - in contrast to mediawiki.
