Welcome to the world of Wikia editors adding and removing line breaks at random. Wikitext elements, for example table definitions, must be the first character(s) on the line in order to be parsed correctly. However, for some unknown reason the Wikia editors (even the source editor) sometimes add or remove line breaks at random points throughout the page when the editor loads, and often your wikitext elements may be unintentionally appended to the line above. When this happens to a table definition, the entire table gets jumbled exactly like yours.

There are only two ways that I know of to get around this happening: one is to preview your edits and and use the Show Changes feature to spot these phantom edits and fix them before publishing. The other is to convert your tables to HTML format, which doesn't have the same positional restrictions as wikitext.
