title: How to get a subset DataTable from another DataTable filtered by few column values?
body: <p>The problem I have is, my search criteria is:</p>
  
  <pre><code>Row["colName"] != "abc"  AND 
  Row["colName"] != "def"  AND 
  Row["colName"] != "ghic"  AND 
  Row["colName"] != "klm"  AND
  Row["colName"] != "xyz"  AND 
  Row["colName"] != "mnp"  etc..
  </code></pre>
  
  <p>in other words, after my research I found something about <code>DefaultView</code> of the <code>DataTable</code> and <code>RowFilter</code>, but <code>Rowfilter</code> seems to  filter only by one value.  </p>
  
  <p>My situation is I need to filter by a bunch of values.</p>
  
  <p>Thanks</p>
