Please note - this property requires the Select extension for DataTables.
This method simply deselects the columns that have been found by the
columns() selector method.
Deselect one or more columns in the table, based on the columns found by the
API instance that contains a reference to the deselected columns.
Deselect all columns which have a class of 'important':
var table = $('#myTable').DataTable(); table.columns('.important').deselect();
