Column¶

Instance of a column in Atlan.

Complete reference

This is a complete reference for the Column object in Atlan, showing every possible property and relationship that can exist for these objects. For an introduction, you probably want to start with:

Snippets — small, atomic examples of single-step use cases.
Patterns — walkthroughs of common multi-step implementation patterns.

Column inherits its attributes and relationships from these other types:
