Abbreviation:  ã|noneã%
 
Parameters:    ã|noneã%
 
    ã|Description:ã%
The \rule  markup skips  a blank  line and  draws a horizontal  line (rule).
Rules are used to  separate material, such as tables or  sections.  No extra
vertical space is skipped  after the rule, so you may  need to add some with
\vs.
 
    ã|Example:ã%
 
\tabletitle{Elements of the Spheres}
\rule
\vs{6pt}
\tabskip 3em plus 3em minus 1em
\halign{\lft{#}&&\rt{#}\hs{20pt}\cr

Oxygen&62.1\phantom{0}&60.6\phantom{0}\cr
Hydrogen&1.1\phantom{0}&0.1\phantom{0}\cr
Aluminum&0.22&11.54\cr}
\rule

    ã|Notes:ã%
If you want  a rule of a different height,  depth, or width than illustrated
with \rule and if you are not using \monospace, then use \hrule.
