After you’ve created a worksheet and begun filling in your data, you might decide to insert a row or column to add data you didn’t think to include when you started. For example, a customer might want to add a product to an order. To accommodate this, you can insert a blank row below the last row in the existing order and add the new item there. If you wanted to add a row in the middle of the existing order data, you could insert a blank row above an existing row. You can perform similar actions with columns: If you want to begin recording a new piece of information about your customers, such as a Web site or e-mail address, you can add a column to store that information. You can even use the Insert Options smart tag to format the new rows or columns.
