Suppose I would like to add the support for column header tooltips to DataTables. For that I pass tooltip column setting to DataTables constructor:

myTable = $("table#report").DataTable({
    "data"         : reports,
    "columns"      : [{
        "title"     : "ID",
        "tooltip"   : "Report ID",
        "data"      : "id"
    }, {
        "title"     : "Comment",
        "tooltip"   : "Report comment",
        "data"      : "comment"
    }],
    ...
});

Now what API can I use to access these extra values? I tried to do this via settings() but I failed. I did it like this:

$(myTable.table().header()).find('th').each(function(index) {
    $(this).attr('title', myTable.context[0].aoColumns[index].tooltip);
});

but I don't like accessing context directly. What could be the better solution? Thanks for any hint in advance,

P.S. I have found this post but it does not provide any nice solution.
