Question: Deleting a column from a DataFrame?

Is the implementation of DataFrames in Maple antiquated compared to PANDAS or other modern implementations of DataFrames? Even doing the most basic tasks is extremely difficult or unintuitive. I have lived in the DataFrame help pages for 5 years and I still can't delete a column from a DataFrame. Will I ever get any work done?
