Sorry, but there is currently not an 'easy' way to delete columns, so you
have go the copy venue. The thing is that table data is row-wise, so
removing a column always implies a complete rewrite of the table.
I'm thinking on implementing a column-wise table object for PyTables so that
these kind of operation would be efficient to do. Probably that would be
implemented in PyTables 3.
