table.putcolkeyword - Function

3.2.1 put a specific keyword for a column


Description

Put a keyword in the given column. The value of the keyword can be a scalar or an array of any type or it can be a record.
It is possible to define a keyword holding a subtable. In that case a special string containing the name of the subtable will be passed to the table client.
It is possible that the value of a keyword is a record itself (arbitrarily deeply nested). A field in such a subrecord can be written by separating the name with dots. If a subrecord does not exist, an error is returned unless makesubrecord=True is given. In such a case intermediate records are created when needed.
