Question

you just finished creating an expense report table, but your boss tells you to create an extra column representing non-production costs. How do you insert this column?

Answer 1

If you are using Microsoft Excel, then that would be easy.
In a spreadsheet, there are rows and columns. Click the row or cell adjacent to the new column that you will be adding. In versions of MS Excel 2007 and up, here's what you are going to do. In Home Tab, you can find "Insert" button. Click "Insert", then select "Insert Sheet Columns."
