To use our running example it looks like:
MALE | JOHN | RED MALE | MARK | BLUE MALE | NIC | GREEN MALE | DAVID | BLUE FEMALE | SARA | ORANGE
I want to display like:MALE: John (red) | Mark (blue) | Nic (Green) | David (Blue)
FEMALE: Sara (orange)
The color isn't an issue, its basically just grouping by a common attribute and displaying it horizontally instead of vertically.

If you have an array of 3 colors named colors (I dont know but, maybe the set tag can build a mapping that works like an array...)
Try this: <!-- initialization --> <c:set var="colorIndex" value="0"/> <!-- loop --> <tr> <td bgcolor="${colors[colorIndex++%3]}" >
In the expression you're coding the round robin (increment and modulus 3) and the selection of the color based on the index.
But, I didn't try it. I hope the modulus is a valid construction in EL.

I'm not exactly sure what you mean with "rotate"?!
Do you just have a collection that you want to iterate - with each each entry corresponding to a "row" in the table? Or shall every row display a different "column" of your table? It's hard to understand from your examples..
For displaying tabular data, you should check out the displaytag-library: http://displaytag.sourceforge.net/ - it has nothing to with jstl, but gives you everything you will likely ever need for displaying tables...

Greetings, I have a table of data that I'd basically like to rotate, is this possible/smart in JSTL? Basically, I have an attribute with three colors, each one is a different row in a table. 001 Blue data 001 Green data 002 Purple data I want to have one row:001 | Blue Data | Green Data | Purple Data. Any suggestions? Please help by pointing me elsewhere if you can.... - Nic
