Q2: excel工作表保护和取消保护的问题
打开要保护的excel
选择“审阅”选项,可以在该页面的工具栏上看到有一个“保护工作表”的工具栏
点击该按钮,打开“保护工作表”对话框。在该对话框中,需要设定一个取消保护工作表时的密码,以及保护工作表后,允许进行的操作,将允许的操作前面的复选框选中,即点击打上“√”
点击“确定”按钮,弹出确定密码的对话框,输入“保护工作表”页面中设定的密码,然后点击确定
此时,如果再在工作表页面中输入数据或修改数据时,会弹出该工作表被保护的提示信息。
当想编辑该文档的时候,执行取消保护工作表操作就可以了。和设定保护工作表时的操作类似,打开要编辑的excel文档,选择审阅,可以看到原来“保护工作表”的工具变为“撤销保护工作表”的工具
点击“撤销保护工作表”按钮,会弹出“撤销保护工作表”对话框,在编辑框中输入设定“保护工作表”时的密码,然后点击“确定”按钮
回到excel工作表编辑区,发现可以编辑文档了。
