Hi,
Perhaps I am not understanding your situation or perhaps my example
failed to stimulate your creativity. ;-)
If you don't know the class, at the minumum the class should implement
something that will spit out the column names, and the way to get the
elements of each row.
For instance, if your model classes all implemented a method that gave
the Contrib table the column metadata it was looking for, it could
return a runtime generated string that looks like this:
"data0:ID:getUserDetails('USERGUID'),data1:Email:getUserDetails('EMAIL'),data2:First
Name:getUserDetails('FIRSTNAME'),data3:Last
Name:getUserDetails('LASTNAME')";
Or more abstractly, the string above is 3 of these, one for each column of data:
"RowIdentifierForTheLoopToReference" + ":"+
"commonMethodForGettingColumnDisplayName()" +":" +
"commonMethodForGettingDataValue()"
The "RowIdentifierForTheLoopToReference" can be anything string, like "cat".
The table will increment the name for each row (row 8 would be "cat8")
So your data model class might have something like this?
Public Abstract Class DataModelBaseClass
{
public String GetStringForContribTableColNames();
public Object GetData(String ColName);
}
I am out of coffee, so I'm going home now. Good luck!

Sorry it doesn't help. As I wrote I don't know column names at development
time. I don't know even the class name because model is created during
runtime. I can give more details if it's not clear
