table.toasciifmt - Function

3.2.1 Write CASA table into an ASCII format
Description

Write a table into an ASCII format approximately compatible with fromascii except that in order to permit variable shaped arrays (as they often occur in MSs), array values are output enclosed in square brackets. The separator between values can be specified and defaults to a blank. Note that columns containing invalid data or record type data are ignored and a warning is issued.

If the argument headerfile is set then the header information is written to that file instead of the first two lines of the data file.
