t:columns does exactly that -- it takes a collection of data and makes as many columns as items in the collection.
In fact, you can think of t:columns as a data table rotated 90 degrees. The t:columns component, like dataTable is a subclass of UIData. The "trick" is that when t:columns renders a "row" it uses <td> instead of <tr>. It's not quite that simple, but from the perspective of an end-user, it can be treated as such. In fact, t:columns API is a little bit confusing since getRowData() really means getColumnData and getRowIndex() really means getColumnIndex(). Again, that's because it's effectively a nested dataTable that renders td tags instead of tr tags. I hope that helps!
