OK, we're way better than we were using strings and println as in days past, but it's still "clunky" creating HTML tables using HtmlTree, addContent, and so on.

HTML tables are complex enough, and we use them often enough, that it is probably worth having an abstraction like a "table builder" to help create HTML tables. The builder would have methods tohelp set caption, summary, headings, and adding rows. And, as part of adding rows, it could take care of setting the background color on alternating rows.
