I am trying to add a table to a field in a specific issue type.

Unfortunately, this renders as plain text when I go to create a ticket from this issue type, rather than a nice tabel that people can add information to. What exactly is going wrong here? Wiki rendering is turned on for this field, also. I have read some things out there about there needing to be extra spaces or new lines in places, but none of those things have worked. Any guidance people can offer would be of great help.
