Table style override 1.0.0

After upgrading from XF 1.5, I had more than 1100 threads that used a custom bbcode to make tables. They looked like this:


Well, the built in TABLE bbcode did not handle that at all, and the raw text (no formatting at all) just showed in these threads. None of the table bbcodes i found could be easily switched to without manually updating a thousand+ posts, or writing a complicated program to convert all the bbcodes to a different format.

So, I wrote the attached code. Now, because of how XF 2.3 treats bbcodes, the [TABLE="xxx"] and [TD="xxx"] just wouldnt work. So I had to do a couple of DB queries to change these.

SQL:


Then i wrote an addon to handle the above. Funny enough, I had to leave the [TR="xxx"] code as it was, as switching it to the same format as the above didnt help.

So, this is VERY niche, and probably not very helpful to anyone. BUT, it does show how to intercept and override the built-in
code, and I hope that it has good educational value.

The screenshots show some sample bbcode, then a rendered table (which only renders at all because of the SQL changes) without the plugin enabled, and finally the same post with the plugin enabled.
