Specify column order in the code representation of a data model

You can specify order of columns in a table when managing data models as code using the order array in the table element.

By specifying column order, you can control how tables created using the Create a data model from a code representation endpoint are presented to users in the UI, allowing you to logically sequence columns left-to-right based on their contents, data types, usage, and more.

Example representation with order

The following example shows a JSON representation of a data model with a table that has a specific column order:

Representing order

In this representation, the column order is specified in the order array of the table element. The order array contains the IDs of the columns and folders in a table in the order you want them to appear in the table, where the first item in the order array is the left-most column in the Sigma UI.
