XL Adding worksheets - Computer Definition
Excel automatically creates three worksheets in each workbook. To add a fourth (or more), right click on a worksheet name tab and select Insert. To delete a worksheet, right click and select Delete.
Tab Placement When a new worksheet is created, its tab is placed to the left of the tab you right clicked. To move a worksheet within a workbook, click on the name tab and drag it to the new location. When selected, the cursor changes to a page icon and a small triangle points to where the worksheet tab will be placed when you let go.
