No code has to be inserted here.

Oh, Oh! I think I found my errors! I was using the first TABLE tag on its own line. So the table above looks like this in the BBcode markup:

PHP Code:
[TABLE]Column 1 | Column 2 | Column 3 | Column4
2|Red|Blue|Green
3|Red|Blue|Yellow
4|Vermillion|Cobalt|Citrine
[/TABLE]
