# Rename a table or change its primary field

`PATCH https://studio.gtable.app/v1/apps/{appId}/tables/{tableId}`

The id never changes, it is the column name and what every rule and page points at.

The name is what people read.

Requires the `schema:write` scope. Operation `tables.update`. MCP tool `tables_update`. CLI, once published: `gtable tables update`.
