Sorting and displaying data objects is facilitated by displaying a collection of tags, each representing a respective data object, and each including identifying information for its respective data object. The organization of the tags with respect to one another is correlated with the organization of the data objects. Responsive to user input, the tags are displayed in a specified arrangement, and a new tag and an associated new data object associated with the new tag are created. A user is permitted to specify parameter values for the new data object, which is added to the existing data objects at a location that corresponds to a location of the new tag within the organization of the tags. The new data table thus includes the new data object arranged in order with the previous data objects as determined by the organization of the tags and the new tag.
