An Image Based Document Management (IBDM) server includes a table generator, a symbolic representation module and a sort engine. The table generator generates a table from the form images, the table comprising cells with data types including image data, symbolic data, image and symbolic data and an empty value, and updates the table. The symbolic representation module converts at least one of the cells with image data to symbolic data. The sort engine determines, from a sort request for a column of the table received from a user, at least a first priority for a first data type, the column including at least two of the data types, determines from the sort request a second priority within one of the data types, and sorts the column according to the sort request.
