The invention provides a field configuration method and device. The method comprises the steps that user table identification is acquired from a user table element data table; a field configuration element data table is searched for according to the user table identification, so that a field configuration element data set is obtained; the field configuration element data set is selected to acquire a configuration field name; newly added data is generated in the field element data table; the field element data table is used for storing element data of configured fields in the data table of the user. According to the field configuration method and device, the user table identification of the current data table is acquired to search for the field configuration element data table, then extended fields of the current data table are selected, related information of the selected extended fields is added to the field element data table, and according the field configuration of the current data table is achieved; when a system loads fields of the current data table, the system can load extended fields by loading the field element data table.
