1. First, you need an Office installation disk or download an installation package. You can use Office2007, Office20 10 or later. For Office2003 and previous versions, installation is not recommended.

2. Open the installer to install. Microsoft OfficeExcel must be installed during the installation process, and other contents can be selected or installed by default without modifying the contents.

3. After the installation is completed, click the right mouse button in the blank space of the desktop and slide to New. There should be an Office Excel. Click on it, and the desktop will automatically create an Excel worksheet file.

4. Every time you need to edit the table in the future, just open this Excel file on the desktop for editing.
