If you go in the admin console to Spaces -> Settings -> Filters and Macros and verify that the Wiki Syntax Filter is set to On?
If it is On, can you take a look at it's settings and verify that it is set to be applied to Body and also that the "Enable wiki table syntax" is set to Yes?
That was right on the money. The body checkbox was not checked. I have no idea how it got turned off, but cest la vie.
