The tabularew environment is similar to tabular (LaTeX kernel) but adds a new command to modify the horizontal alignment in certain circumstances. It solves the problem of centering multicolumn headings when they are wider than the text underneath them. (In a tabular environment they are aligned to the left, even if they contain a "c" in their preamble.) It is actually a workaround for a (mis)feature of TeX alignment algorithm. Comments and suggestions are welcome, especially for the user interface. Diego Saba diegosaba at gmail dot com
