# AWS::Cassandra::Table Column
<a name="aws-properties-cassandra-table-column"></a>

The name and data type of an individual column in a table. In addition to the data type, you can also use the following two keywords:
+ `STATIC` if the table has a clustering column. Static columns store values that are shared by all rows in the same partition.
+ `FROZEN` for collection data types. In frozen collections the values of the collection are serialized into a single immutable value, and Amazon Keyspaces treats them like a `BLOB`.

## Syntax
<a name="aws-properties-cassandra-table-column-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-cassandra-table-column-syntax.json"></a>

```
{
  "[ColumnName](#cfn-cassandra-table-column-columnname)" : String,
  "[ColumnType](#cfn-cassandra-table-column-columntype)" : String
}
```

### YAML
<a name="aws-properties-cassandra-table-column-syntax.yaml"></a>

```
  [ColumnName](#cfn-cassandra-table-column-columnname): String
  [ColumnType](#cfn-cassandra-table-column-columntype): String
```
