Table details
Read a table's schema, properties, and data preview.
Select a table in the catalog tree to open its detail pane. The breadcrumb spells out its identity — warehouse, namespace, table — and an Iceberg table has four tabs: Preview, Schema, Properties, and Permissions.
Preview
About the first 20 rows, read straight from the table’s current snapshot — a sample, not a query result:
- A badge counts the rows shown, and a truncated to first parquet file badge appears when the table holds more than the preview shows.
- Empty and edge states say so directly, e.g. Empty table — no snapshots yet.
To read a table for real — every row, filtered, or joined — use a notebook or SQL Lab.
Schema
The table’s columns: name, type, whether it is Required, whether it is an Identifier field, and a description if it has one.
Properties
The table’s metadata: storage location, table UUID, Iceberg format version, current snapshot, and last-updated time, plus any table properties. The current snapshot is the version every engine reads by default — see Iceberg tables.
Permissions
Who is granted what on this table, directly and inherited from further up the tree. See data permissions.
Tables that are not Iceberg
A generic table — registered in the catalog but not Iceberg, such as a folder of files or a Delta table — has no snapshots or schema, so there is nothing to preview. It shows two tabs instead: Dataset (format, location, and any properties) and Permissions.
