Demo done at last: see here. It took a bit longer than expected.
It takes a slightly different approach to the example above. They get to the same end, so aren’t in opposition, but alternatives. for later readers use either/both as suits your work.
The above works off generating an HTML table that Excel can treat as a data table. The demo I just uploaded takes a more old-school approach and exports a tab-delim text file for use in Excel or other tab-delim consuming formats.
