# 保护工作表

Protects the cells in the current sheet from being modified. Choose Tools - Protect Sheet to open the Protect Sheet dialog in which you then specify sheet protection with or without a password.

要访问此命令...

Choose Tools - Protect Sheet.

要防止单元格被编辑，则必须选中 格式 - 单元格 - 单元格保护选项卡页面上的已保护复选框，“单元格保护”选项卡页面也可以通过上下文菜单中的 单元格格式 打开。

Unprotected cells or cell ranges can be set up on a protected sheet by using the Tools - Protect Sheet and Format - Cells - Cell Protection menus:

1. 选择要取消保护的单元格

2. 选择 格式 - 单元格 - 单元格保护。取消选中已保护复选框，然后单击确定。

3. On the Tools - Protect Sheet menu, activate protection for the sheet. Effective immediately, only the cell range you selected in step 1 can be edited.

To later change an unprotected area to a protected area, select the range. Next, on the Format - Cells - Cell Protection tab page, check the Protected box. Finally, choose the Tools - Protect Sheet menu. The previously editable range is now protected.

工作表保护还影响屏幕下方工作表选项卡的上下文菜单。不能选择删除和重命名命令。

如果工作表受到保护，则无法修改或删除任何单元格样式。

A protected sheet or cell range can no longer be modified until this protection is disabled. To disable the protection, choose the Tools - Protect Sheet command. If no password was set, the sheet protection is immediately disabled. If the sheet was password protected, the Remove Protection dialog opens, where you must enter the password.

受保护的工作表经过保存后，只能使用 文件 - 另存为 命令来重新保存。

## Password (optional)

Allows you to enter a password to protect the sheet from unauthorized changes.

Complete protection of your work can be achieved by combining the options Tools - Protect Sheet and Tools - Protect Spreadsheet, including password protection. To prohibit opening the document altogether, in the Save dialog mark the Save with password box before you click the Save button.
