The correct sequence for deleting a column in MS Excel 365 is:
1. Select the column header: Click on the letter at the top of the column you want to delete. This will select the entire column.
2. Right-click: Right-click on the selected column header.
3. Choose "Delete": In the context menu that appears, select the "Delete" option.
4. Choose "Entire column": In the Delete dialog box, make sure "Entire column" is selected (it usually is by default).
5. Click "OK": The selected column will be deleted from your spreadsheet.
This method ensures that the entire column is removed, including all cells and their contents within that column.
