Obviously there has to be limits. Oracle and Informix will be less restrictive than Access.
Do you really need 255 columns or fields? For example, when importing from elsewhere. Would you reconsider changing the design? If importanting, can you import in stages? For example importing with VBA code and splitting the data with logic in the code. This is similar to GoDawgs [\b] suggestion, or split it up into relational tables.
Good luck on this one.
