I would like to have multiple rows of column headers which groups column headers according to a group. I'd like the output to look something like:
+-----+---------+---------+ | | group 1 | group 2 | | +----+----+----+----| | Day | h1 | h2 | h3 | h4 | =========================== | Mon | 1,1| 1,2| 1,3| 1,4| | | 2,1| 2,2| 2,3| 2,4| | Tues| 3,1| 3,2| 3,3| 3,4| --------------------------- In other words, Day is the first <th>, it has a rowspan=2. "group 1" has a colspan=2, and group 2 also has a colspan=2. There's an empty <th> in the second <tr>, then <th> cells for h1..h4. I'm thinking it would be along the lines of the groupBy="true" in the <t:column> tag, or perhaps combined with a more complex DataModel than just a ListDataModel wrapping a collection of Strings. Since I want to use groupBy="true" for the rows too, I can't just flip the axis, otherwise that would be an easy solution. Any and all help is appreciated! Thanks! Coop
