Export columns are not as expected

Export columns are not as expected

Datatables v1.12.1
Test Case: https://jsfiddle.net/Cyberjetx/hgvtqxux/50/

Description of problem: When setting the exported columns with the excel class to limit export you will get all of the columns even though we have omited cols 0 & 5 from export. If you filter column visibility in any way that hides omited columns, then, the column(s) hidden will be excluded from export.

"columnDefs": [  
    { targets: [0, 1], className: 'noVis' /* No Hiding */ },
    { targets: [1, 2, 3, 4], className: 'excel' /* export all but name & salary */ }
]

...

exportOptions: {
    columns: [':visible(.excel)'],
}

What have I missed in my setup?

    I don't thing the :visible selector can take parameters can it? This is the jQuery docs on it and there is no indication of that.

    It works but oddly. '.excel:visible' works as a jQuery selector in the console but breaks the export.

    I desire to export only visible .excel columns.

    I was thinking that I could use the .on('column-visibility.dt' to modify the class to something I can toggle eg excelOff or something. Or is there a better datatables centric way to do it?

    I tried to make class changes when the columns were toggled.

    This is a fail too. I believe is is because I am modding the dom outside datatables' purview.

    Any ideas?

    UPDATE: columns: [':visible.excel'], is working as expected. I also tried .filter() but that also broke the export.

    I hope this helps the lurkers.

    I wonder if this is valuable as an export option switch, maybe IncludeHidden true by default. It could be too much of a one off though.
