Caution! - these methods are not functional over the table accessed by ODBC.
If working with non-existing table (or non-existing database) the PmaDatabase object must be closed e.g. by the PmaDatabase.Close method (methods PmaDatabase.Open,... cannot be used and also the "On start" configurator must be set on value Don't connect the database and don't open the table or it is necessary to close the table and the database by the PmaDatabase.Close method before calling the PmaDatabase.Create method).
var oDb = pMe.Pm("/Database");
oDb.CreateField("columnText", 10, 180); //10 - string
oDb.CreateField("columnBool", 1, 0); //1 = Boolean
oDb.CreateField("columnReal", 6, 0); //6 = Single
oDb.CreateField("columnTime", 8, 0); //8 = Date
Thus created table can be treated in a standard way.
