How to Add a Field to a Table?

A new field expands your Custom Data table structure. In v2 you can use the full Custom Data model editor or the quick path from the records table via Add field.

When Needed

You need to store additional information in table rows.
You want a field type such as email, link, operator, or tag.
You need a new column quickly without opening every editor tab.

What's Important to Know

A field is a column with a data type and label; the technical key is generated automatically (or set in advanced mode).
The semantic type (text, number, email, table link, operator, etc.) drives validation and display.
After you save the structure, existing rows get an empty value in the new field unless you set a Default value.
Structural changes may show Review changes before save.

Prerequisites

You opened Menu → Custom Data.
The table already exists.
You know the type and label for the new field.

Step-by-Step (full editor)

In Custom Data tables, select the table → Edit.
On the Fields tab, click Add field.
Choose Type and enter Label.
Optionally expand the field card:
- Default value, Required, Unique values, View only.
- For links — Link to table; for platform directories — a system type (operator, subject, tag, etc.).
On Field display, enable Table and/or Card if the column should be visible immediately.
Click Save. Confirm Review changes before save if it appears.

Quick add from records view

Open the table from Tables.
In the toolbar, click Add field.
In the Add field dialog, choose Field type, Label, and optionally Default value.
For advanced settings, click Open full editor.
Confirm — the field appears in the table; existing rows will have empty values in the new column.

What Happens Next

The field is part of the table structure. New and existing rows can be filled in the table or record card.

How to Verify

The field appears on the Fields tab in the editor.
The column shows in the records table (if Table is enabled).
A test row saves without validation errors.
