tableindex - Constructor

Construct a tableindex

Synopsis
tableindex(tab, columns, sort)

Description
Construct an index for the given table. The names of one or more scalar columns forming the index have to be given. If a single name is given, the column can be an array column too. Normally a sort will be done to get the key values in the correct order. If the table is already in the order of the data in the given columns, the argument sort can be set to F to avoid needless sorting.
