public interface TableDataSet
extends DataSet

A DataSet implementation for 3 dimensional z(x,y) data sets where the data is arranged in a sequence of tables. Each table will have a set of monotonically increasing x tags and y tags. The x tags for all the tables, when taken together in the order that the table are in, will be monotonically increasing over the whole data set. The y tags are constant over the y scans of each table, but may change, either in number or value, from table to table.
