How to Load the table Dynamically

I am new to DynamoDB.I am using Unity 2019. I am loading the table (HighLevelTableExample.cs)
through this method.

DynamoDBTable("mydynamodbtablename")]
public class HighLevelTableExample : DynamoDbBaseExample
{
public string S_tablefieldset;

.... }

Actually i have to dynamically Load a table . That means

DynamoDBTabl(MyDesiredTable)]

Instead of hotcode the table name. When i pass the table name in arguments. The table should load . How can i do it.
