1、LEFT:从左至右返回指定个数的字符 =LEFT(text, num_chars) 例:left("hello", 2) = "he" 2、RIGHT:从右至左返回指定个数的字符 =RIGHT(text, num_chars) 例:right("hello", 2) = "lo" 3、MID:从指定位置起返回指定长度的字符 =MID(test, start_num, num_chars) *例:MID("hello", 2, ...
两个函数公式得出的结果不一样,这是因为在FIND函数中,“雨”位于“吴雨峰”串中的第二个位置,故返回“2”;而在FINDB函数中,每个汉字按2个字节算,所以“雨”是从第三个字节开始的,返回“3”。 同理:LEFT与LEFTB、RIGHT与RIGHTB、LEN与LENB、MID与MIDB、REPLACE与REPLACEB、SEARCH与SEARCHB的关系也如是。即...
=left(a1,len(a1)-2)右面用上面的公式=right(a1,len(a1)-2)左边取值，用这个两个公式都支持，不规则长度的单元格数值，下拉从左数第三位数开始取值：=value(right(a1,len(a1)-2)) 可取不包含左边两位的其余部分如果要取左起前两位，那么=value(left(a1,2))从右数第三位数开始取值：(可取右...
