# AWS::S3Tables::TableBucket
<a name="aws-resource-s3tables-tablebucket"></a>

Creates a table bucket. For more information, see [Creating a table bucket](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-tables-buckets-create.html) in the *Amazon Simple Storage Service User Guide*.

Permissions  
+ You must have the `s3tables:CreateTableBucket` permission to use this operation. 
+ If you use this operation with the optional `encryptionConfiguration` parameter you must have the `s3tables:PutTableBucketEncryption` permission.

 AWS Cloud Development Kit (AWS CDK)   
To use S3 Tables AWS CDK constructs, add the `@aws-cdk/aws-s3tables-alpha` dependency with one of the following options:  
+ NPM: `npm i @aws-cdk/aws-s3tables-alpha`
+ Yarn:`yarn add @aws-cdk/aws-s3tables-alpha`
