This table is divided into three parts. The top part contains the symbols
provided by LATEX; the last command, \leadsto, requires the latexsym
package. The middle table contains the AMS arrows; they all require the
amssymb package. The bottom table lists the negated arrow symbols;
they also require  amssymb.
