Okay a little update..
You could do it with BB codes...
i did a test as you can see on the screenshots...

Attachment 107828
BBcodes i added :
table :
Code:
<table border="{option}">{param}</table>
used like this
Code:
[table=1]content[/table]
the =1 is border line.
tr :
used like this
Code:
[table=1][tr]content[/tr][/table]
td :
used like this
Code:
[table=1][tr][td]content[td][/tr][/table]
and a complete exsample..
Code:
[table=1]
[tr]
[td]Colum 1[/td]
[td]Colum 2[/td]
[/tr]
[tr]
[td]----------------------------------[/td]
[/tr]
[tr]
[td]test 1[/td]
[td]test 2[/td]
[/tr]
[/table]
which is the one you see on the image attached.
its not user friendly, but i dont think you want users to make tables, incase they forget to close a tag or something, which could ruin the style on that specifik post.
