Adding Individual Column Filter

[ikarius6]

After updating to last version of IgnitedDatatables, the useful plugin "ColumnFilter" stop working, so we can recovery the filter functions with:

var mytable = $('#mytable').DataTable({
... //server_side config
});

$('#mytable tfoot th').each( function () {
    var title = $('#mytable thead th').eq( $(this).index() ).text();
    $(this).html( '<input type="text" placeholder="Search '+title+'" />' );
});

mytable.columns().eq( 0 ).each( function ( colIdx ) {
    $( 'input', mytable.column( colIdx ).footer() ).on( 'keyup change', function () {
        mytable
            .column( colIdx )
            .search( this.value )
            .draw();
    });
});

And the code is not invasive, you can filter with search input and be more specific with individual column search inputs.
