colspan not working with single head row

TobiasBg

According to https://datatables.net/examples/basic_init/complex_header, colspan is fully support in header rows.
This is working well in that example, obviously, where the header has multiple rows.

However, if a <thead> only has a single <tr> with cells that use colspan, a JavaScript error is raised.

Here is a test case with a single header row and one colspanned cell in it:

However, when duplicating the row (I prepared that as a HTML comment in the test case), everything works fine again.

That's unexpected. Thanks for letting me know. I'll take a look into it.
