How to delete entire column if it is Empty

I have columns
Row 1 is heading..


IF Column C doesn't have data in entire column then delete C D E F
IF Column D doesn't have data in entire column then delete D E F
IF Column E doesn't have data in entire column then delete E F
IF Column F doesn't have data in entire column then delete F


Same way for heading NN's

IF Column G doesn't have data in entire column then delete G H I J K L M N
IF Column H doesn't have data in entire column then delete H I J K L M N
IF Column I doesn't have data in entire column then delete I J K L M N
IF Column J doesn't have data in entire column then delete J K L M N
IF Column K doesn't have data in entire column then delete K L M N
IF Column L doesn't have data in entire column then delete L M N
IF Column M doesn't have data in entire column then delete M N
IF Column N doesn't have data in entire column then delete N
