You will need customization and use the export options:

https://datatables.net/reference/api/buttons.exportData()
https://datatables.net/extensions/buttons/examples/html5/columns.html

If you take a look at this thread you would need "customizeData" to add further rows to print / export.

It is described here in the docs:

Something like this could be the structure of it:

exportOptions: {
    columns: function(column, data, node) {
        if (column > 17) { //no export of columns > 17
            return false;
        }
        return true;
    },
    modifier: { selected: null }, //export all rows not only the selected ones
    format: {
        body: function ( data, row, column, node ) {
           ... do something            
            return data;
        },
        header: function ( data, column ) {
            ... do something            
            return data;
        },
        footer: function ( data, column ) {
            ... do something            
            return data;
        }
    },
    customizeData: function (data) {
        ... manipulate the data object
    }
}
