how do I mod this to make the text into an <a href link ?
thought I understood the columns.map(function (column) {...} but when I try to modify it doesn't work. I can produce <a href ... text appearing as text within the elements, but not as working links.
I feel I need to add another dom element and attribute, but can't combine the columns.map(function (column) {..} with adding an element.
