GNU R package for advanced html tables

 The htmlTable package provides tables with state-of-the-art layout
 elements such as row spanners, column spanners, table spanners,
 zebra striping, and more. While allowing advanced layout, the underlying
 css-structure is simple in order to maximize compatibility with word
 processors such as 'MS Word' or 'LibreOffice'. The package also contains
 a few text formatting functions that help outputting text compatible with
 HTML/'LaTeX'.
