Creates a new custom table together with its columns in a single request. Requires the acting user to be an owner-admin. The tab value is the target tab's page ID; use Custom Fields > List Custom Fields (list-custom-fields) to find the pageId of an existing field on the desired tab. Use this to create a table backed by multiple columns. For adding a column to a table that already exists, use Create Custom Table Field (create-public-custom-table-field) instead. For a single standalone field not backed by a table, use Custom Fields > Create Custom Field (create-public-custom-field) instead.
