title: Validate Each Column of dataTable using HashTable
body: <p>I have a datatable whose columns are lets say col1,col2,col3
  Now I want to validate each column value whether its 0 or not</p>
  
  <p>I do not want to use if else clause that will be writing to much stuff.</p>
  
  <p>Is there any possibility to do the same task using HashTable or something else ?</p>
