Oh, that should be simpler than I thought, then. Just make a UDF that takes the field and formats the result according to some rule.
I think that the real question is, depending on what condition do you want to change the display format? Depending on the answer to that question, you will put the formatting options into different places.
A certain field always uses a certain format: some sort of data dictionary.
The same field will appear different for different users (depends on user preferences): some table that stores user preferences.
The same field will appear different between different records, depending on some additional criteria: either deduce the formatting from other fields, or store an additional field for the display options.
There are probably some other combinations possible, too.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
