What about using a query to do so ?

ALTER TABLE "paradox_table.db" ADD [column_name] data_type

where data_type is one of the following:

alpha, number, money, short, long integer, BCD, date, time, timestamp, memo, formatted memo, graphic, OLE, logical, autoincrement, binary, and bytes

begin
  Query1.SQL.Text := 'ALTER TABLE customer ADD myfield char(40)';
  Query1.ExecSQL;
end;
