Hello, dear friends...
I'm trying to add dynamically a calculated field to a TTable object and it
don't work !!!
I have a class TMyTable = Class (TTable) which I open dynamically.I want to
add a Calculated StringField to this table by program...
Thanks a lot in advance.
Pierre.
Sorry for my very bad english !!!

here is an example but don't forget you still need to handle the
calcualted field in your tables onCalcFields event.

 Table1.Active:=false; // Must be false to add Fields to the Dataset
  Table1.FieldDefs.Update; // Make sure we have the latest Fields

  Monthly:=TFloatField.Create(Table1);
  Monthly.FieldName:='Monthly Salary';
  Monthly.Calculated:=true;
  Monthly.Dataset:=Table1;
  Monthly.DisplayFormat:='$#,0.00';

  Table1.Active:=true;
