Workaround for datatable.getColumn(node) (#2531924)

gistfile1.js

// Add support for table.getColumn( node )
Y.DataTable.prototype.getColumn = (function (original) {
    return function (seed) {
        var cell;

        if (Y.instanceof(seed, Y.Node)) {
            cell = this.getCell(seed);

            seed = cell && (cell.get('className').match(
                new RegExp(this.getClassName('col', '(\\w+)'))) || [])[1];
        }

        return original.call(this, seed);
    };
})(Y.DataTable.prototype.getColumn);
