To select one field, click that field's row selector.
To select a group of fields, drag through the row selectors of those fields.
Click Delete Row on the toolbar.
Notes
If other database objects contain references to a deleted field, you need to delete those references as well. For example, if a report includes a control bound to a deleted field, Microsoft Access won't be able to find the data from the field and will generate a message.
You can't delete a field that's part of a relationship. You must delete the relationship first.
