Do not think so.
But, depending on your purpose, it may be sufficient to force a monotype font (e.g. Courier) using the [font]
tag, and then simply "draw" your table by hand using ASCII characters. For example:
[font=courier]
-----------------
| Col A | Col B |
-----------------
| 1 | X |
| 2 | Y |
| 3 | Z |
-----------------
[/font]
Certainly, it is troublesome and may be considered dirty, but your set of available tools is pretty limited.
