This chapter explains how to produce tables like this one:
tables. @Index { tables }
@CD @Tbl
   aindent { ctr }
   arulebelow { double }
   aformat { @StartHSpan @Cell @B X | | @HSpan }
   bformat { @Cell rr { no } @I A | @Cell rl { no } B | @Cell C }
   rule { yes }
{
@Rowa
   X { Value of mathematical formulae (millions of dollars) }
@Rowb
   A { Quadratic formula }
   B { @Eq { x ^= { minus b +- sqrt { b sup 2 - 4ac } } over 2a } }
   C { 3^.5 }
@Rowb
   A { Binomial theorem }
   B { @Eq { ( a + b ) sup n ^= big sum from k=0 to infty
matrix atleft { ( } atright { ) } { n above k } a sup k b sup n-k
} }
   C { 12^ }
}
As the example shows, the tables may contain spanning columns, aligned
columns, and rules, and the cells may contain arbitrary objects.
