Thanks, but grouping headers is not it. I thought I saw a demo where you can have regular columns, but then the cell data can span the columns. As an example, here the data spans 3 columns:

|      City         |                   State          |              Zip         |
|San Francisco, CA 94102                                               |
|Boston, MA 12110                                                            |

You can still click on any column header to sort on that field.

Thanks again,

Walter

That is it!!! It’s perfect for names (like your demo) and addresses. I can try to build this in pure JS, or if you have time, Tony, to port it over, very much appreciated!
