This reimplementation of the tabular and array environments re-does what the array package does, but in a way that builds on a reimplementation of the tabular and array functionality within the LaTeX kernel itself. Among many improvements claimed for the package is that there are no built-in column types: all column types are explicitly declared within the package.

The package is part of the mdwtools bundle.
