Defines a tabular column type for formatting numerical columns in LaTeX. The column type enables numerical items to be right justified relative to each other, while centred beneath the column label. In addition, macros are provided to enable variations on this column type to be defined. Usage of the package is superficially similar to that of dcolumn; however, the alignment scheme is different, and the packages have different, though overlapping, applications.
