Example

  1. Create a DataTable variable called dt.
  2. Add a Generate Data Table inside the initial Sequence.
  3. In the Generate DataTable Data Table field under Properties, add the dt variable.
  4. In the ColumnSeparators field under Properties, write ";", and in the NewLineSeparator field, write "|".
  5. In the Generate Data Table Input field, type "1; Nicole|2; John|3; Michael". This would be the sample values inside the data table.
  6. Add an Add Data Column activity.
  7. In the Add Data Column DataTable field, add the dt variable.
  8. In the Add Data Column Column Name field, write "Age"

    The use case should look as the following screenshot:


Initially, the DataTable should only have 2 columns, but after execution, a column named Age should be added.
