Your code snippets are confusing but it looks like you are using colspan in the header. This is supported by Datatables but you also need a header row with one th for each column. See this Complex header example for more details. Also look at the HTML requirements docs to make sure you are providing an HTML table that Datatables supports.

If you still need help please post a link to your page or a test case replicating the issue so we an help debug.
