How to to export hidden columns to PDF file?

borstate

It works fine with xls file using
"sExtends": "xls",
"mColumns": [0, 1, 2, 3, 4, 5, 6, 7, 8, 10] (where [10] is hidden)
in PDF column [10] is overwritten and messed up.
PDF displays properly only visible columns
Here is snippet where I setup column [10] is not visible
"aoColumnDefs": [
{
"bVisible": false, "aTargets": [10]
}
]

Thank you in advance.
