kvitable (hackage): Allows creation of a table from a set of of Key+Value Indices. This differs from the standard Map structure in that the Map simply indexes by value but the KVI table indexes by a heterogeneous list of keys along with their associated values. This effectively creates an N-dimensional table, where N=Product(Count(Values[key])).  The table contents can be sparse.  This library also provides the ability to format multi-dimensional data in a table presentation.  The table is automatically formatted and can be output in a number of different styles (ascii, html, etc.)  Multi-dimensional data is more difficult to represent than simple two-dimensional data; this package provides the ability to select which dimensions should be represented as sub-rows and which dimensions should be represented as sub-columns.
