title: DataTables - dynamically set columns searchable
body: <p>I need to set the <a href="http://www.datatables.net/reference/option/columns.searchable" rel="nofollow">searchable</a> property of a column dynamicaly (after table init). Is there a solution? The use-case is, that I'm using the button extension to toggle column-visibility. But I wan't that only visibile columns are searched.</p>
