show/hide columns inside custom search filter ($.fn.dataTable.ext.search)

Hi, I'm trying to figure out how to show or hide columns when the custom filter $.fn.dataTable.ext.search is triggered:
$.fn.dataTable.ext.search.push
(
function( settings, data, dataIndex )
{
// show/hide columns in here
}
);
Is it possible?
Thanks.

Why would you show / hide columns inside a filtering function? That function is called once for every row in the table on a search action. It could be done (
new $.fn.dataTable.Api(settings).column(...).visible(...)), but it seems hugely inefficient.I don’t actually understand what the goal is here I’m afraid?

Oh I see what you mean, you're right my bad, I only want to show it once if selected filter is active.

I'm with you now - thanks for the explanation. And I agree - that listener would be a good way to do it.
