The bundle provides a Python script that interprets a higher-level language for specifying table constraints: you write a program in that langage, and the helper script emits the LaTeX code you need for your table.

Strong points of the script are in balancing the width of columns in terms of the total amount of text they contain (but see also the tabulary package), and the design of sparse tables (where rather few values need to be entered).
