I cannot unhide columns

[Ninny]

I have hidden columns E through to O, but now I cannot unhide them.
Any ideas? In very simple form please!

Select both columns D and P.

Right click within that selection.
Select Unhide

I have now found how to fix that problem - by selecting column to the
right and dragging it to the left. Then the unhide works.
Further problem now......... I am now trying to delete a field, and it
won't let me!!!
Any help please.
