There is not a direct way to delete a row/column from a table. However, it is feasible with the following workaround: 

  1. Using the "Excel" Actions, write the data table to a Microsoft Excel worksheet ("Write to Excel Worksheet" Action). 
  2. Use the "Delete Row/Column from Excel Worksheet" Action to delete the desired column. 
  3. Store the result into another data table variable with the "Read from Excel Worksheet" Action.
