A way to add a new column to existing table in DynamoDB in Amazon's AWS:

We can store the values in DynamoDb in 2 ways, (i) In an RDBMS Type of Structure for the DynamoDB, we can add a new Coulmn by executing the same command keeping the "new Column" entry within which the Records in the Existing Table has been created. we can use DynamoDb with the Records/ Rows having Values for certain Columns while other columns does not have Values.

(ii) In a NoSQL kind of Structure; where we store a Json String within a Column to keep all the attributes as per the Requirement. Here we are generating a json string and we have to add the new Attribute into the json String which can then be inserted into the same Column but with the new Attribute.
