The cell in column A, row 1 is addressed as A1. You can address a range of adjacent cells by first entering the coordinates of the upper left cell of the area, then a colon followed by the coordinates of the lower right cell.
A1表示的是位于列A行1处的单元格。要描述一个单元格区域，只要在给出这个单元格区域左上角处的单元格位置后键入双引号，随后给出这个单元格区域右下角处的单元格位置即可。比如：由工作表左上角处的四个单元格所组成的单元格区域可以命名为A1:B2。
