centered tables

[Werner LEMBERG]

How can I center a multicolumn table?  Using @display ... @end display
doesn't work.  Without centering, it looks really ugly in the DVI
file.

Of course, I could use a leading invisible column, but...

BTW, is there a command to insert a vertical resp. horizontal line in
tables?  Both could easily be supported in virtually all output
formats.

Finally, a small bug report: Doing @i{text @samp{a}} produces bad
output.  I suggest that the quotes used in @samp are always roman
quotes and not italic ones.
