Hi,
Currently it is not possible to individually set the thickness of the
different borders of a frame. A typical use-case is typesetting a table
row where the top frame is double the thichness of the bottom frame.
Having to resort to metapost for something as simple as this is a bit
annoying.
Attached is a metapost library that defines "local" fences and allows you
to set border individually. For example
\defineframed[...][frame=off, topframe=local, topframethickness=1pt,
bottomframe=local, bottomframethickness=0.5pt]
sets the top frame to be 1pt and the bottomframe to be 0.5pt.
Does it make sense to include this (appropriately modified) in the core?
Or is it better to distribute such enhancements as a user module.
