title: Selected columns from DataTable
body: <p>How to get the Selected columns form the DataTable? <br>For e.g my BaseTable has three columns, <br>ColumnA, <br>ColumnB and <br>ColumnC. <br><br>Now as part of intermediate operations, I need to retrieve all the rows only from the ColumnA. Is there any predefined formula just like <strong>DataTable.Select?</strong></p>
