title: DynamicTableEntity PartitionKey and RowKey
body: <p>I create DynamicTableEntity as follows:</p>
  
  <pre><code>string env = "envTest";
  stting ver = "1.0";
  siring id = "12356";
  string mode = "verify";
  DynamicTableEntity entryEntity = DynamicTableEntity(env,ver);
  entryEntity.Properties.Add("Id", id);
  entryEntity.Properties.Add("Mode", mode);
  </code></pre>
  
  <p>As a result created a table with columns:"Id", "Mode", "PartitionKey", "RowKey"
  I want to change the names of "PartitionKey", "RowKey", i.e. I want the env to be a partitionKey but but The column name to be "Env". How can I do it?</p>
