The #addColumn method appends the column to the end of the table
automatically. Much like a SQL database, inserting a new column somewhere
in the middle of the table is, at best, going to be resource intensive.
Plus, with DataViews available, there is virtually no reason to care about
the order of the columns in a DataTable (beyond knowing which is which). I
would avoid using #insertColumn and stick with #addColumn. The third one
(insertColumnAfter) doesn't exist.
