title: Add more colums to the table and input values in dynamoDB JS shell
body: <p>I have created a table in dynamoDB JS shell with stu_id as the hash_key_attribute.</p>
  
  <pre><code>var params = {
      TableName: 'student_test',
      KeySchema: [ 
          { // Required HASH type attribute
              AttributeName: 'stu_id',
              KeyType: 'HASH',
          },
      ],
      AttributeDefinitions: [ 
          {
              AttributeName: 'stu_id',
              AttributeType: 'N',             },
      ],
      ProvisionedThroughput: { // required provisioned throughput for the table
          ReadCapacityUnits: 1, 
          WriteCapacityUnits: 1, 
      },
  };
  dynamodb.createTable(params, function(err, data) {
      if (err) ppJson(err); // an error occurred
      else ppJson(data); // successful response
  
  });
  </code></pre>
  
  <p>Now I want to add stu_name and school columns and insert the values. Tried defining the column names in GlobalSecondaryIndexes but it didn't work.</p>
  
  <p>I am using DynamoDB local.</p>
