Suggestion: Right-Click -> Delete Column on tables

[Reelix]

On tables, as it stands, you can left-click the column title, click the "Delete Column" radio button, and click the OK button.

I suggest an alternative way of being able to do this by right-clicking anywhere in the column itself (Body, or possibly title as well). Doing this, there is currently an option to delete rows, although I feel that it would be intuitive to also use this dialog to delete the column as well.
