DataTables: Cannot read property style of undefined

Question

I am getting this error with the following:

jquery.dataTables.js:4089 Uncaught TypeError: Cannot read property \'style\' of undefined(…)
_fnCalculateColumnWi         


        

Answer 1

The problem is that the number of tags need to match the number of columns in the configuration (the array with the key "columns"). If there are fewer tags than columns specified, you get this slightly cryptical error message.

(the correct answer is already present as a comment but I'm repeating it as an answer so it's easier to find - I didn't see the comments)
