# Update a Table

Call `PUT /reporting/datamodels/{datamodel_id}/datasets/{dataset_id}/tables/{table_id}`. The following example uses the same definition as the [Create/Add a Table](/products/customer-data-platform/treasure-insights/create-or-add-a-table) POST API.

For the API endpoint, select the appropriate [endpoint for your region](https://api-docs.treasuredata.com/en/overview/aboutendpoints/#treasure-data-sites-and-baseurls).
