This is going to sound like a real newbie type question...
How do you center a column heading in a datatable. What I need to do is center the column heading but have the data be right aligned. I can't get the heading to act one way (center) and the column to act another (right aligned).
Actually, it's usually enough to define a table headerClass attribute with centering, then define the columnClass for that column with right, left, or center alignment depending on what looks best for that column.
I do that all the time, such as when displaying columns with currency values (right-aligned) and text values (left-aligned), often centering items like dates and Y/N value columns.
Sometimes the only way things ever got fixed is because people became uncomfortable.
