Add

$pattern[6] = "/\[lrtable\](.+?)::(.+?)\[\/lrtable\]/s";
$replacement[6] = '<table><tr><td valign="top">\\1</td><td valign="top">\\2</td></tr></table>';

to bb_codes.php

Use it this way:
[lrtable]Left side::Right side[/lrtable]
Of course you can make "Left side" or "Right side" another lrtable ;-)

That may be not the most comfortable way for users, but maybe moderators want to give their postings a little extra flavour :-)

nice one :)

Tables BB code

You can even add width=xx to the first <td> tag for better formatting with

$pattern[7] = "/\[lrtable(=)?(\d{1,3})?\]
(.+?)::(.+?)\[\/lrtable\]/s";
$replacement[7] = '<table><tr><td valign="top" width=\\2>\\3</td><td valign="top">\\4</td></tr></table>';

[lrtable=60]Left side::Right side[/lrtable]
will produce a 60 pixels wide left column, while the other uses what it needs.

Maybe I'll rewrite this some day to support real tables, not only for left-right
