Detete columns with Datatables and fixedColumns.

ColinGM

Getting this error when trying to remove column index from variable cols holding the dynamic column data.

ie: cols.splice(cellIndex, 1);

TypeError: col is undefined
if ( ! col._setter ) {

in jquery.dataTables1.10.3.js

The datatables is based on this code found here http://jsfiddle.net/4nil/zq7j97c4/
which was from a previous question on dynamically adding columns.

Thank you for any support you can offer.
