tablecloseall - Function

close all open table tool objects

Synopsis
tablecloseall()

Description
It can easily happen that a table tool object is overwritten which may leave open the underlying table object. For instance:

  t := table('a.b')
  t := table('c.d')

overwrites t and leaves open table a.b.

This function closes all open table objects, thus also all open tables for which a valid tool object still exists.

Returns
Bool
