Coop,
This was asked before. Maybe the previous solutions could help you?

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
