Allows access to a column in a table


Description
This is a convenience tool for access to a table column. It offers the same functionality as the column access functions in the table tool (e.g. getcell). The advantage is that the column name does not need to be specified each time.



Example
include "table.g"
vis:=table("3C273XC1.MS", readonly=T);
vistimc:=tablecolumn(vis,"TIME");
vistimc.getcol();
vistimc.done();
