The tabstackengine Package The tabstackengine package provides a front end to the stackengine package, to allow tabbed stacking. In most cases, an existing stackengine command may be prepended with the word "tabbed", "align" or "tabular" to create a new tabbed version of a stacking macro. Additionally, hooks are provided into the package's parser, so that (completely outside of any stacking constructions) tabbed strings of data may be parsed, extracted, and reconstituted. Steven B.
