datatables + hiding all columns button

Question

in datatables I want to be able to hide all columns, but can't seem to get the syntax right.

This from the code below and the above link, creates a button that shows all the columns. Is there a way to write this so that I can hide all columns?

        {
            extend: 'colvisGroup',
            text: 'Show all',
            show: ':hidden'
        }

code:

$(document).ready(function() {
    $('#example').DataTable( {
        dom: 'Bfrtip',
        buttons: [
            {
                extend: 'colvisGroup',
                text: 'Office info',
                show: [ 1, 2 ],
                hide: [ 3, 4, 5 ]
            },
            {
                extend: 'colvisGroup',
                text: 'HR info',
                show: [ 3, 4, 5 ],
                hide: [ 1, 2 ]
            },
            {
                extend: 'colvisGroup',
                text: 'Show all',
                show: ':hidden'
            }
        ]
    } );
} );

i have tried something like the below with other permutations, but no joy, can anyone advise, and/or how I might find it in the documentation.

{
    extend: 'colvisGroup',
    text: 'Show None',
    visibility: false
}

Answer 1

{
    extend: 'colvisGroup',
    text: 'Show None',
    hide: [':gt(1)'],
    //show: [0, 1, 2],
    //hide: [0, 1, 2],
    //hide: ['*']
}

this worked for me, only 2 column visible...
