Hello,
I understand that currently you have records selected in the Attribute Table and are interested in exporting only those records to a stand-alone table to view/edit in Microsoft Access. Is that correct?
If so, in the Attribute Table in ArcMap 10, go to Table Options > Export. By default, the selected records only will be exported. Click the browse button > and for the 'Save as type:' specify a dBase table. This will create a stand-alone dbf table that can be opened in Access.
I hope this information helps.
Thank you.
