Can't get row or column spans to work.

[sebunger]

Hi, I'm trying to create a table with a column span, but I can't seem to get it to work at all. Even the table that's given as an example in the documentation doesn't work:

seb@eragon:~[0]$ cat grid_table.txt 
+---------------------+----------+
| Property            | Earth    |
+=============+=======+==========+
|             | min   | -89.2 °C |
| Temperature +-------+----------+
| 1961-1990   | mean  | 14 °C    |
|             +-------+----------+
|             | min   | 56.7 °C  |
+-------------+-------+----------+
