NOTE that this works for FILE GEODATABASE FEATURE CLASSSES, and NOT layer files. What I did was have a set of layer files in my map for viewing, and then another folder within the TOC called "Query-able layers" and put the feature classes in there.
FYI - This also works well with the Query Builder (part of the basic build) as users can first see the associated attribute table before they write a query. It also gives them the ability to view the results of the query in tabular format! Something that was conspicuously missing from build 1750, though earlier versions (900) did yeild a tabular list of features when a query was ran. Not sure what you are using the table viewer for, but it sure helped me with queries.
