This chapter explains how to produce tables like this one:
tables. @Index { tables }
@CD @Tab
   hmargin { 0.4c }
   vmargin { 0.3v }
   side { single }
   @Fmta { @Col @B @CC X @Over A,B,C }
   @Fmtb { @Col @I A ! @Col B !! @Col C }
{
@Rowa
   above { single }
   X { Value of mathematical formulae (millions of dollars) }
@Rowb
   above { double }
   A { Quadratic formula }
   B { @Eq { x ^= { minus b +- sqrt { b sup 2 - 4ac } } over 2a } }
   C { 3^.5 }
@Rowb
   below { single }
   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 entries may be arbitrary objects.
