Danielgsc,
You should be able to use BBCode in the cells. Use {br} to do a new line without starting a new row.
Try this for the code:
[table=head]number|column 1|[b]column 2[/b]|[i]column 3[/i]
1|[table]this|is|a
small|table|inside
the|big|table[/table]|[b][color=red]hallo[/color][/b]|[size=3][b][color=blue]everything is possible[/color][/b][/size]
2|[url="http://www.google.com"]visit Google?[/url]|[quote=Zitat]small quote[/quote]|:D :) 8)
3|wanna have a list?[list][*]list 1[*] list 2[*] list 3[/list]|[left]align left[/left]{br}[center]align center[/center]{br}[right]align right[/right]|contact me: [email]example@example.net[/email][/table]
