r-cran-gtable - 0.3.1+dfsg-1 main

A grob table captures all the information needed to layout grobs in a
table structure. It supports row and column spanning, offers some
tools to automatically figure out the correct dimensions, and makes it
easy to align and combine multiple tables.
Each grob is put in its own viewport - grobs in the same location are
not combined into one cell. Each grob takes up the entire cell viewport
so justification control is not available.
