The Workspace Tables pane in DataStudio gives you a centralized view of all tables in your workspace. From this pane, you can browse tables by folder or compute engine, search by engine type, environment, or name, create new tables, import data, and modify existing table configurations.
Prerequisites
Before you begin, ensure that you have:
Required folders and layers created in your workspace. Folders group tables by use case or category; layers classify data by processing stage. See Manage settings for tables
A data source added and associated with DataStudio, with compute engine metadata collected
Task Reference Add a MaxCompute data source Add a MaxCompute data source Add a Hologres data source Add a Hologres data source Add an AnalyticDB for PostgreSQL data source Add an AnalyticDB for PostgreSQL data source Add an AnalyticDB for MySQL V3.0 data source Add an AnalyticDB for MySQL V3.0 data source Add a ClickHouse data source Add a ClickHouse data source Register an EMR cluster Register an EMR cluster to DataWorks Register a CDH or CDP cluster Register a CDH or CDP cluster to DataWorks Associate a data source with DataStudio Preparations before data development: Associate a data source or a cluster with DataStudio Collect compute engine metadata Metadata collection
Open the Workspace Tables pane
Log on to the DataWorks console. In the top navigation bar, select a region. In the left-side navigation pane, choose Data Development and Governance > Data Development.
Select your workspace from the drop-down list, then click Go to Data Development.
In the left-side navigation pane, click Workspace Tables.
Browse and search for tables
The pane offers two views:
View by Table Theme — organizes tables by folder
View Metadata by Engine — organizes tables by compute engine. Note that only MaxCompute and Hologres compute engines support the View Metadata by Engine dimension.
To find a specific table, filter by compute engine type, environment, or table name. The pane displays up to 5,000 tables by default. If your workspace exceeds this limit, use search and filter options to locate the table you need.
The following screenshot shows an example search using the MaxCompute engine.
Environment availability by workspace mode:
| Workspace mode | Development environment | Production environment |
|---|---|---|
| Standard mode | Available | Available |
| Basic mode | — | Available |
Create a table
In the Workspace Tables pane, click the 
icon to create a table.
The following compute engines are supported:
| Table type | Reference |
|---|---|
| MaxCompute | Create and manage MaxCompute tables |
| AnalyticDB for PostgreSQL | Create an AnalyticDB for PostgreSQL table |
| EMR | Create an EMR table |
| Hologres internal table | Create a Hologres internal table |
| Hologres external table | Create a Hologres external table |
To import data after creating a table, click the 
icon. For details, see Import data to a MaxCompute table.
Modify a table
In the Workspace Tables pane, double-click the table name to open its configuration tab.
Edit the table configuration as needed.
Commit the table to the target environment to apply your changes.
The following compute engines support table modification:
| Table type | Reference |
|---|---|
| MaxCompute | Create and manage MaxCompute tables |
| AnalyticDB for PostgreSQL | Create an AnalyticDB for PostgreSQL table |
| EMR | Create an EMR table |
| Hologres internal table | Create a Hologres internal table |
| Hologres external table | Create a Hologres external table |
