Cell references can let you refer to ranges of cells 单元格引用可引用单元格区域。
If a cell on another worksheet or workbook refers to the selected cell , a special icon appears to indicate that fact ( the other workbook must be open in order for it to be traced ) 如果另一工作表或工作簿中的单元格引用了选定的单元格,此时就会显示一特殊图标以说明此情况(为方便追踪,必须打开另一工作簿) 。
